Essays About Biology: Top 5 Best Examples and 6 Prompts

Writing essays about biology can be difficult because it’s composed of many subtopics. Check out this article for our top essay examples and writing prompts.

Biology came from the Greek words “bios” (life) and “logos” (study). It’s why biology is the study of life or living organisms. Aside from being a natural science, it also has consolidated themes, such as cells making all organisms. Because it’s a broad topic, biology is divided into specialized fields such as botany, genetics, zoology, microbiology, medicine, and ecology. 

Biologists consider living beings’ origin, evolution, growth, function, structure, and distribution. It’s a comprehensive subject, so there are many things you can write about in your essay. However, at the same time, you might find it challenging to focus on just one area. 

Below are examples to give you an idea of how to write your essays about biology:


1. Essay About Biology by Kelli Wilkins

2. my interests in biology by anonymous on, 3. essay on the importance of study of biology by akhila mol, 4. what biology means to me by anonymous on, 5. how my biology teacher changed my perspective of learning the subject by sankalan bhattacharya, 1. biology in my everyday life, 2. something i realized because of biology, 3. my memorable biology class experience, 4. genetics’ role in people’s diseases, 5. my experience during the pandemic, 6. biology and health.

“Studying Biology is important for a number of reasons, but in particular because it is used in every field. If we did not have a good understanding of Biology then nobody would be able to understand how bodies work, and how life on earth functions.”

Wilkins shares her desire to study anatomy, a branch of biology, and expounds on what makes biology an essential field. Because biology lets people know more about the world, she digs into why she’s interested in anatomy, specifically to find ways to cure illnesses and develop technologies to discover new treatments. She ends her essay by relating biology to the existence of doctors and hospitals. 

“It is known that education plays an important role in the life of any individual. It gives an opportunity to develop personality and gain specific skills, to get profound knowledge and experience in order to apply them practically in the future. As for me, my major goal is to study Biology in order to get appropriate knowledge and skills required for my future profession.”

The author shares why they want to study biology, referring to the human body as the “perfect machine” and curious about how it performs each of its systems’ functions. The writer also mentions how biology is critical to their future profession. They aim to help people with their health problems and relay their desire to research the brain to find more data on it. 

“The study of biology owes great significance in human life, because man for its day-to-day requirements is dependent on plants and animals either directly or indirectly.”

Mol lists seven reasons why humans need biology in their daily lives. Her list includes health, diseases, agriculture, horticulture, food, animal breeding, and entertainment. She expounds on each point and how they affect a man during his time on Earth. She explains each relationship in a simple manner that’s easy to understand for the readers.

“Without biology, we would have no idea about an organism’s makeup, or the most basic unit of life, a cell… Biology influences me in many ways. Biology influences me by teaching me why to take care of the environment, why I am to take care of my body, and by giving me a better overall view of all scientific areas of study.”

In this short essay, the writer lists down reasons why biology is essential. These reasons include taking care of the environment, one’s body, and others. The author also expounds on their reasons by presenting facts supporting biology’s importance to the world and human lives.

“He told that the syllabus may be a good way to prepare for an exam but our knowledge should not be limited to any syllabus and the questions that were asked in the examination were related to the topic only. He told that if we try to know things in detail and understand them properly then the interest in the subject will develop, otherwise, students will not treat the subject as a subject of their choice. 

Bhattacharya shares his experience with a teacher with a unique teaching style. His Biology teacher from Class 7, before the era of the internet, don’t just carry one book to get all his lessons from. Instead, he has a notebook with the collated information from many books to teach his class. 

Bhattacharya’s teacher taught them things that were not in the curriculum, even if following the curriculum would give him higher points in his evaluation. He only wanted his students to learn more and share with them why learning differs from just knowing.

6 Prompts for Essays About Biology

Prompts for essays about biology

You don’t have to be a biology student to write an essay about the subject. If you’re looking for easy prompts to write about, here are some to get you started:

If mitochondria are the powerhouse of the cell, who is the powerhouse of your classroom? Your home? Relate a biology topic to a similar structure in your life, then explain why you think they are the same. 

For instance, you can compare your mother to mitochondria which generate the energy needed to power a cell. The cell being you. You can say that she gives you energy every day by being there and supporting you in whatever way she can. This prompt bodes for a creative and intriguing essay.

Relay a lesson you learned from biology and how it perfectly explained something you were once hesitant about. Such as being insecure about your big ears – only to know from a biology trivia that ears never stop growing. You can then share how this help lessen your insecurity because you now know large ears are normal. 

Do you have a memory you won’t forget that happened during biology class? Narrate this story and explain why it’s something that left an impression on you. To give you an idea, you can talk about the first time you dissected an animal, where you first realized how complex organisms are and that they are made of many systems to function, no matter how small.

Gene action and heredity are evolving. If you have a genetic illness or know someone who has it, you can share your experience. Then explain what your genes have to do with the disease. Is it something you got from your parents? Did they inherit it from your grandparents? Finally, you can add what your parents’ and grandparents’ lives were like because of the disease.

Virology, another branch of biology, studies viruses and viral diseases. A recent example is the coronavirus pandemic, where more people realized the importance of knowing a virus’ origin, structure, and how they work. Write an essay where you explain how the pandemic operates, such as why people should wear masks, social distance, etc.

For this essay, you can write about how biology helps you care for your health. For example, you can include how biology helped doctors give you the appropriate diagnosis, how you had the opportunity to have the proper treatment, etc. 

If you want to write on a related topic, here are essay topics about nature you can consider for your next essay.

160 Biology Essay Topics

For most science courses, assignments are generally lab-based and rarely require much writing. However, all of that changes in biology courses when detailed essays must be written to highlight a student’s understanding of the subject. These essays are highly technical, with specific comments required to meet the factual nature of the subject.

In addition to meeting the factual requirements needed to complete the assignment, biology essays must also be written in a writing style that is informative and authoritative rather than subjective and personal.

These detailed specifics of writing a biology essay can make completing the writing difficult from the very beginning. Fortunately, we’ve created this guide to help students learn how to write a biology essay. In addition, we’ve also included 160 biology essay topics to help inspire the creative writing process.

How to Write a Biology Essay?

Writing a biology essay starts with choosing a topic. If your teacher has not already assigned a specific topic, then students must choose one that is broad enough to find credible resources and specific enough that the research won’t overtake the writing process.

To select a suitable topic for a biology essay, consider the type of biology class you are taking, the current and previous chapters studied, and the overall context of the course. These factors will help you select a topic that is likely to be relevant to your teacher’s needs and to the passing of your course.

Once students have selected a suitable topic, it’s time to research credible resources that will support the subject. To do this successfully, students need to consider the following:

  • What information is already known about this topic?
  • What topics are related or similar to this topic?
  • Who are credible authors that can explain this topic?
  • What additional sources will provide me with the information needed to complete this assignment successfully?

For example, if you want to write a biology essay on protein synthesis and its regulation at the transcriptional level, research material would include books, articles, and other written works published by credible authors or publishers. While important, this material isn’t the only type of research that should be completed.

Students may also consider consulting medical and biology dictionaries, textbooks, online research databases such as PubMed or Medline, and professional organizations for biologists to find additional sources. Once the research has been completed, it’s time to create the first draft of the biology essay.

Biology Essay Introduction

Starting an essay is always the same. Students should open with a catchy hook statement that introduces an interesting fact, presents a unique perspective, or raises a thought-provoking question.

Once that sentence has been created, students can use the middle part of the introduction to introduce fundamental concepts and provide background details about the topic.

Once that information has been laid out, and the reader knows the necessary details to make the reading interesting and worthwhile, students should move into the final portion of the introduction that answers the question: WHY is this essay important? This question is answered in the form of a thesis statement that details the essay’s overall purpose.

Biology Essay Body Paragraphs

The body paragraphs of your essay will contain the bulk of your research. Be sure that each body paragraph meets the following requirements:

  • One clear idea represented per paragraph or section
  • Examples that back up the point of the paragraph
  • A clear and logical flow between paragraphs with transition words

Make sure that the body paragraphs only contain information pertinent to the subject or topic. Avoid fluff or filler words and phrases that don’t add any substance or value to the writing.

The number of paragraphs in the body may vary depending on the assignment parameters and the essay style. For example, an essay with a 1000 word limit won’t have as many body paragraphs as an essay with a high word count.

Additionally, a compare and contrast essay that examines the similarities and differences between two or more biology concepts may have more body paragraphs than an argumentative essay.

Biology Essay Conclusion

The final section of a biology essay is the conclusion. In this section, students need to summarize the major points of the essay and the overall purpose for writing it. The thesis should also be re-stated to recap what has been learned from the writing.

In addition to these sentences, students should include a final remark about their research and findings. This might be a thought that ties into the intro or another interesting angle that presents a new way of looking at your topic.

Once the conclusion is completed, students should edit and review their work. Make sure that the essay is free of grammar and spelling mistakes before submitting it for grading.

When it comes to choosing a biology essay topic, it is not always as easy as it seems. For students looking for help with writing a biology essay, we have compiled a list of 160 biology essay topics that will hopefully give you some great ideas.

How to Write a Biology Essay

Studying natural sciences and biology in particular, you’ll deal with essays as one of the ways to assess your knowledge and skills. Professors believe that this assignment helps students to develop their skills regardless of the major you pursue. Future biologists should organize their ideas in a structured and transparent manner, using reliable sources and persuasive examples to support your perspective. Even if you’ll work in laboratories, you will deal with written reports.

What is a Biology Essay?

Select the topic for your essay, select a research question, create an outline, essay introduction, thesis statement, essay conclusion, citation and references, look for samples, practice your writing, plan your writing process, ask for feedback, appropriate language for complexity science, writing services, editing proofreading services, what is biology as science, what is the importance of biology in our life, major concepts and topics in biology.

Don’t worry if you don’t have enough experience and doubt your ability to deliver a perfect paper. We have prepared useful tips to help you write a killer biology essay and deliver it on time.

A biology essay is a piece of student writing where you provide arguments and ideas concerning a particular biological topic.

There are various academic essay types, and you can adhere to one of them. For example, you can write a descriptive paper explaining a biological subject. Or an argumentative paper, providing evidence to support your point of view. One of the most common essay types is a cause and effect piece where you explain the reasons and the consequences of some events. You can also come up with the “how-to” instruction or a detailed analysis . The concrete type depends on your professor’s requirements and your preference.

How to Write a Good Essay in Biology

Some people consider writing an art process. However, it is a work that requires your time and effort. You should organize the whole process if you want to get the desired result. There is a step-by-step instruction to follow.

If you want to get a good grade, it is important not only to make your paper informative but also enjoyable. It depends on the topic you choose. And it is crucial to stay on something that you wish to explore. Try to find something you want to investigate.

It is not easy because you may have many ideas in your head, but once you start writing, they disappear. That’s why studying at college, you should always have a notebook at hand, to write down things that come to mind.

The most effective way to select the topic is a brainstorming technique. Let your brain provide you with 30-50 decent options, and then research to create the shortlist with the best ones.

Writing a biology essay, you should use a scientific approach. Come up with a research question you want to answer in your paper. Of course, you shouldn’t choose something too complicated that it is impossible to work through in terms of one piece. It shouldn’t be too obvious as well. Connect your research question with the topic.

Starting a paper, you should have a clear plan to follow. Most student papers have a 5-paragraph structure with specific instructions. It would be almost impossible to keep the main idea and develop good arguments if you just begin. It would help if you started with the outline to keep it in mind when writing.

Don’t worry about how it looks. Nobody will check your plan (if your professor didn’t ask you to deliver it as well). You can organize your thoughts the way you like. Sketches, paints, mind maps, and so on. Use anything you need to make your paper structured. Get rid of all ideas that don’t work for your research question, even if they seem reasonable. You may use them in another paper.

Whenever you need it, you can make some amends and correct your outline.

It is the first paragraph that is intended to attract the readers’ attention. Writing it, you should consider your target audience.

If you’re preparing a paper for newbies, you should provide some basic knowledge, interesting facts, and statistics to introduce the topic.

However, the experienced audience may find such an introduction a bit boring. They already know the main point, and they have a single question: why is this topic important? So, you should provide them with an explanation of why you have chosen this issue and which directions you see for further development.

The introduction finishes with the thesis. It is your research question or the statement you’re going to develop in the body paragraphs. In other words, you should synthesize the overall essay, meaning just in one sentence. It will explain to your readers what the paper is about and your point of view. Without a strong thesis statement, the whole piece becomes useless, given that the audience cannot understand your position.

Body paragraphs are the essay core because they are most voluminous and informative. Once you’ve grabbed the readers’ attention, you should provide them with food for thought.

In a classic 5-paragraph essay structure body takes 3 paragraphs. Each of them is intended to reveal just one idea. You need to provide a short thesis, an explanation, and an example to illustrate your point.

It would help if you were very attentive in writing the essay body because it is easy to lose your way. This is where your outline may be helpful.

Once your readers finish the paper, they have a question “So what?” If you leave them with it, you’ll fail. Your task is to provide an answer to explain how the audience can use the information you’ve written in the body.

Don’t use any new data; just conclude the thoughts you’ve already declared. Are they important in any sense? Can readers conduct their research and gain more insights? Should they be more attentive to environmental issues?

You’ve written a paper with a particular goal (except for getting a good grade), so show your readers whether you’ve achieved it.

Most academic papers require authors to provide additional information. For example, a list of references you’ve used. It is impossible to write a biology essay without data from books, websites, research papers, and so on. And if you use any journal or other source, you should cite it correctly since, in the other case, your piece would be considered plagiarism.

You should adhere to a particular citation style. When it comes to biology, the academic society uses the APA and the CSE format. Make sure you know what style your professor prefers. You also need a relevant guide with all requirements to follow.

Some Essay Tips for Successful Writing

Whatever major you pursue, you’ll deal with written assignments that affect your academic performance. That’s why you need to develop your writing skills. Here you’ll find some actionable tips to follow.

If you want to write well, you should read well. There are various modern sources where you can find many biology papers. It goes about scientific books and journals, specific web-portals. Don’t undervalue the fiction literature as well. You need to understand how other people write and to learn from them.

Once you’ve noticed something interesting that is worth your attention, write it down. You may use these notes in your future writings.

Coming up with a perfect piece, you should understand what the “perfect” stands for. Please take a look at some essays or a research paper example and analyze them.

It doesn’t mean that all samples that are published online are excellent. They have advantages and disadvantages, and you should mention them.

However, don’t copy and paste these samples. Your paper should be unique, and it goes not about paraphrasing some sentences only. The ideas and concepts you use should be fresh as well. Even if you’re just a student, without tremendous research opportunities, you may look at the issue from an interesting angle. Essay samples will show you the right direction.

You shouldn’t expect that your first paper will be outstanding. You have to submit dozens of poor essays until you succeed. It means you should use any opportunity to write something. Whether it is a note, a blog post, a lab report, or an experiment description, you should master your ability to formulate thoughts and choose the best words to convey your ideas.

Don’t leave these texts without attention since you can’t become a better writer if you don’t know your mistakes. Find a mentor who will provide you with essential tips. There are many useful resources online, and you can always hire a professional tutor who will support you.

You can’t sit and wait for the inspiration. Your professor won’t understand the excuse that you aren't in an appropriate mood to write a paper. Therefore you should be able to organize yourself and the work process.

Firstly, define stages, e.g., the research stage, the introduction writing, and so on. Think about how many times you’re going to devote to each of them and include these tasks in your calendar. You can use different strategies, starting with the most complicated part, or, vice versa, from the easiest one. It doesn’t matter if you’re able to provide a good result.

It is also important to get rid of all distractors in advance. Switch off your smartphone and make sure you have anything you need to come up with a paper. It won’t leave the space for procrastination.

People are usually biased when it goes to work. You can’t define for sure whether your biology essay deserves an A-grade. And it would be the wrong decision to wait until your professor spoils your academic performance. You can then discuss your writing with your friends, fellow students, instructors at the college club. If you think someone can provide you with professional assistance, ask for it. Feedback will show your strengths to focus on and weaknesses to work out.

Writing a research paper, you should use a language of scientific thought to explain your ideas. Think about the audience and its level of education. If your paper is full of specific terms, most readers won’t understand it. However, it should not be too simple at the same time since you’re a future biologist and should speak this language at a decent level.

It is also important to know all requirements and follow them. Each paper has its features, so make sure you understand the essay, analysis paper, or a lab report format before writing.

Biology is a science that studies our life in different ways. Students learn about organisms and living creatures that inhabit the planet, their functions, behavior, interaction, and their individual and historical development.

Modern biology covers various sub-topics, such as virology that studies viruses, botany that studies plants, the anatomy that studies the human’s body, etc. Some students choose a particular direction to work in, but all these subjects are united. It would be best if you had morphology and genetics knowledge to succeed with microbiology, and vice versa.

Writing a biology essay, you should think about their final purpose. Some papers are intended to provide people with a fresh look, e.g., when you find exciting information and want to share it with your colleagues. At the same time, you can write a paper for people who don’t have solid biology knowledge. These essays will be very different, so you need to approach this task with all responsibility.

Biology knowledge is important regardless of your career plans. Many facets point to this. First, this science is mainly studying life that is surrounding us. Second, it is important to have an understanding of how all organisms interact with each other. And the next reason that is no less important is the diversity of our life. Thanks to biology knowledge, people treat illnesses, improve food quality, and take care of the whole ecosystem.

It is the study of life that helps people shape the world and provides them with answers that explain why things happen.

Studying biology, you’ll deal with the following topics:

  • Cellular structure and function;
  • Evolution and natural selection;
  • Heredity and genetics;
  • Ecosystems and interdependence.

Many concepts are accepted by modern biology science. These are ideas and understandings that professors want you to remember. For example, all organisms share a standard set of important life processes. It goes about movement, respiration, reproduction, nutrition, and others. All organisms use the same genetic system to maintain continuity. The next essential concept is about species that arise, change, and become extinct over time. Diverse adaptations are the reason why evolution results and ensures survival.

Writing your paper, you should show your knowledge and understanding of significant biology concepts and topics. It would be an excellent platform to create powerful, evidence-based content.

Before doing that, you need to know some good topics for the research paper . They should be suitable for biology students rather than cutting-edge researchers. On , we provide as many biology research paper examples as possible so that you have a huge choice.

What Is Biology? What Topics Might Biologists Study?

Biology is simply the study of everything that has a form of life. It includes investigations on plants, animals, and everything found in the environment. It is about studying how life forms grow, develop, and interact with each other. Biology essay topics for research encompass all these and more.

This science uncovers many fields where various life forms are studied. It makes sense to look through these fields to help you decide which suits you the best.

Plant Biology research topics are about studying the plants around us. They disclose information about their existence as a part of the ecosystem, their life cycle, resources they can give us, their ability to preserve them from climate changes, and so on. There are many ideas to choose from, but you must focus on a specific one.

Human Biology research topics are all about us. These topics focus on different body parts, such as the human brain, the human immunological system, the nervous system, etc. In addition, you can discuss DNA modifications in humans and explain why genetic disorders occur in your research projects. Various cell research is also common today.

Biology research topics on the environment are in great demand too. For example, climate change is becoming a more significant threat every day. By studying environmental topics in biology for projects and research, we can come up with ways to combat them and preserve ecosystems.

Microbiology research topics delve into things we can’t see. There are trillions of microbes and bacteria all around us. Knowing about them is essential to understanding what makes us sick and how to fight against them. All microbiology research paper topics are pretty complicated yet very engaging to include in your paper research.

Molecular biology topics dive even deeper into the level of atoms and molecules. The various medicines and drugs we take were all created through molecular-biology research. It is one of the areas full of ideas, but there is yet to be much evidence. Science is advancing in this realm but still needs a lot of time. Topics of molecular biology will need days for research only.

Keep in mind that there are more ideas and variations of this science. We offer more examples in further sections of the article about developmental biology, marine biology, evolutionary biology, etc. Explore them and make your writing appealing and meaningful in the eyes of a professor.

How to Choose a Topic for Biology Research Paper?

When choosing a biology project topic, you must be aware of one or more fields of science. Biology research is critical to the present world. By doing research, we can learn more about genetic disorders, immune disorders, mental health, natural disease resistance, etc. Knowing about each of these could save lives in the future.

For those who may not have the time or resources to do their own research, there are research paper writing services that can provide assistance with the project. And we are always here to help you find your own topic among interesting biology research topics. Here we prepared some useful tips to follow.

  • Tip 1: The level of interest matters Pay attention to one that interests you, and you might have ideas on how to develop the topic. Passion is fundamental in research, after all.
  • Tip 2: Explore the topic Try to narrow things down a bit. If the topic is too broad, you may not be able to cover all aspects of it in one research paper. If it is too narrow, the paper could end up too short. Analyze the topic and the ways to approach it. By doing so, you can strike a balance between the two.
  • Tip 3: Discover the recent developments To make your research paper touchable with the present day, you must explore the latest developments in the field. You can find out what kind of research has been done recently by looking at journals. Check out research papers, topics, research articles, and other sources.
  • Tip 4: Ensure to get enough resources When choosing a topic, make sure it has plenty of resources available. For example, a research paper on xenobiology or cutting-edge nanobiology might sound attractive. Still, you might have difficulties getting data and resources for those unless you are a researcher at a government lab. Data, resources, complex numbers, and statistics are all invaluable to writing a paper about these topics.

That is why we have selected a range of biological topics. The topics on this list are all hopefully exciting topics for research you could write an excellent paper on. We should also add that easy biology topics to research are rare, and a writer usually needs days to prepare and start writing. Yes, biology research topics for high school students are a bit easier, but still, they need time to explore them.

On the other hand, biology research topics for college students are far more complex and detailed. Some people prefer evolutionary biology research paper topics, and we can agree with this claim. These research areas do have a lot of potential and a lot of data to support the claims. Others prefer cell biology research topics that are a bit specific and fun. Anyway, with this article’s list of easy biology research topics, you will surely find the one matching your interest.

For those who may not have the time or resources to do their own research, there are provide assistance with the project.

Tips on How to Write a Biology Essay

How to Write a Biology Essay

In this article, we will guide you on how to write a perfect biology essay from scratch. You’ll find various tips to help you excel in writing your essay and creating a paper worth the highest grades. We also prepared a jellyfish essay example for you, so it can be easier to enhance all the specifics and structure of this kind of paper.

What is Biology Essay

A biology essay is a student-written work where you present arguments and ideas about a particular biological topic. The essay on biology can take different forms like argumentative, cause-and-effect, descriptive, detailed analysis, or ‘how-to’ instruction, depending on the professor’s guidelines and writer’s preferences. 

A descriptive paper can explain a biological subject, while an argumentative one provides evidence to support a point of view. It’s up to you to choose which type is more suitable for the topic you’re writing about. The most common type is a cause-and-effect essay explaining an event’s reasons and consequences. 

How to Craft a Perfect Essay About Biology

Writing is an art form that requires time and effort. But if you prefer someone else to write the paper for you, you can just text the experts, ‘ do my homework for me ,’ and consider it done. 

Here is the step by step instruction to organize the process for desired results. 

How to Craft a Perfect Essay About Biology

Choose Your Biology Essay Topic

To get a good grade:

  • make your paper informative and enjoyable by choosing a topic you wish to explore. 
  • Use a brainstorming technique to generate 30-50 options for biology essay topics and research to create a shortlist. 
  • Keep a notebook to jot down your ideas.

Choose a Question for Research

When writing a biology essay, use a scientific approach by selecting a research question related to your topic. Always avoid overly complex or apparent questions. You can also text our profs ‘ write my research paper ,’ and it can be done in a blink.

Create an Outline

Always have a clear plan when writing biology essays while starting a paper. Use a 5-paragraph structure with an outline to keep your main idea and arguments organized. Use any format that works best for you and adjust as needed. Discard any ideas that don’t fit your research question.

Use a Strong Thesis Statement

The introduction should end with a strong thesis statement synthesizing the overall essay, conveying the research question and your point of view. The paper is ineffective without a clear thesis, as readers may not understand your position.

Use Citation and References

Include a list of references in your academic papers, such as biology essays, to avoid plagiarism and provide data sources. Use the appropriate citation style, like APA or CSE, and consult a guide for requirements.

How to Structure a Biology Essay

Ensure your essay has an attention-grabbing introduction, a detailed body, and a solid conclusion with distinct sections. Use around seven paragraphs for the main body, adjusting as needed for the required word count.

Biology Essay Introduction

In the introduction of your essay about biology, showcase your expertise by providing a brief background of the topic and stating the essay’s objective. For a research paper, explain why the study is relevant. Make sure the reader understands the essence of your subject.

The body section of your essay on biology should focus on supporting and defending your thesis statement. To achieve this, make a list of essential points to cover and address each one step by step. Starting a new paragraph for each point ensures neatness and a continuous flow. 

In conclusion, restate your thesis statement and summarize supporting points to solidify your arguments. Avoid introducing new concepts, and leave a lasting impression on your instructor.

Jellyfish Essay - Example of a Biology Essay About a Fascinating Creature of the Ocean

Jellyfish, also known as jellies, are incredible creatures of the ocean. They’re members of the phylum Cnidaria, including corals and sea anemones. You can find jellyfish in every ocean around the globe, from the surface to the depths of the sea. 

Do you know what shape the jellyfish body has?! It’s one of their most unique features. Their bell-shaped body comprises a soft, jelly-like substance called mesoglea, found between two cellular layers. The outer layer of cells, the epidermis, is thin and flexible, while the inner layer, the gastrodermis, contains the jellyfish’s digestive system. At the bottom of the bell is the mouth, surrounded by tentacles armed with stinging cells called nematocysts. 

The jellyfish tentacles consist of venom-filled sacs, which can be potentially dangerous and life-threatening. Considering the severity of its sting, researchers have gathered information on how to treat it effectively. Use thick clothing, tweezers, sticks, or gloves to alleviate the sting. It’s crucial to avoid touching the sting with bare skin since the venom can cause severe harm. Always dispose of the tool used for removing the sting to prevent re-stinging. 

Jellyfish are creatures that feed on small fish and other tiny marine organisms. They capture their prey using the tentacles and bring it to their mouth. Once the food is inside the jellyfish, it’s broken down by digestive enzymes and absorbed into the gastrovascular cavity. 

An exciting thing about jelly is its life cycle. They go through several stages of development, starting as a tiny, free-swimming larva and then growing into a polyp. The polyp stage is stationary, and the jellyfish attaches itself to a surface using a sticky pad. During this stage, the jellyfish reproduces asexually, creating clones of itself. These clones then break off from the polyp and develop into the familiar bell-shaped body of the adult jellyfish. 

Jellyfish play an essential role in the ocean’s ecosystem too. They’re a food source for many marine creatures, including sea turtles and some fish species. They also help to control the population of tiny marine animals by feeding on them, and their waste products contribute to the nutrient cycle in the ocean.

However, jellyfish populations can sometimes explode and become a nuisance. This phenomenon mostly occurs when their natural predators are eliminated from the ecosystem or when water conditions, like temperature and salinity, are conducive for jellyfish growth. In cases where jellyfish populations reach excessive levels, they can clog fishing nets and interfere with other human activities in the ocean.

Jellyfish really are stunning creatures of the ocean. They’re diverse, with many different species, and are essential to the marine ecosystem. While they can sometimes become a nuisance, they’re vital to the ocean’s food web and nutrient cycle. Studying jellyfish can give us a greater understanding of the complex and interconnected systems that make up our oceans.

Practical Tips for Creating Perfect Academic Papers

Developing writing skills is crucial for your academic success regardless of your major. Check out these tips we provided for improving your writing. But if you aren't fond of writing, you can easily hand it to professionals by saying, ‘ do homework for me .’

Search for Samples or Examples

To improve your writing, analyze examples of well-written biology essays or research papers. Although not all online samples are perfect, they can still provide insights into what works and what doesn’t. However, avoid plagiarism and ensure your paper is original by presenting fresh ideas and a unique perspective. 

Read Whenever You Can

Develop your writing skills by reading widely and extensively. Look for biology papers in scientific journals, websites, or books. Don’t forget to take notes on interesting points that you can use in your papers later.

Practice Makes Perfect

Don’t expect to write a perfect paper on your first try, so take every opportunity to practice your writing. Find a mentor if needed and use online resources to learn from your mistakes and improve your skills.

Always Organize Your Writing Process

Organize your work process instead of waiting for inspiration by defining stages, scheduling time for each task, and eliminating distractions. Don’t wait for mood to write an essay about biology; use different strategies to overcome writer’s block.

Proofread and Get Other Feedback

It’s hard to assess your own work accurately. Seek feedback from peers or instructors to identify strengths and weaknesses to improve upon. Don’t wait for your professor’s feedback to know if your biology essay is good.
