Have you ever noticed how interesting the study of biology is? As life forms, it’s incredible how we and all other forms of life are entwined with organic substances that sustain us in surviving and thriving. The study of biology spawns many interesting topics for essays and research papers.

Simply put, Biology is the study of living things. The core biology knowledge covers various aspects of living beings like chemical components, structure, and how they act under different conditions. It is beneficial to understand these facts if you write an essay on biology. Here are some topics that will help you out in writing your essay.

10. Ethology (the study of animal behavior)
11. Phycology (the study of algae)
12. Ecology (the scientific examination of ecosystems and interactions between organisms and their environment)
13. Molecular biology (the science that deals with the structure, function, growth, reproduction, evolution, and genetics of living organisms at the level of molecules such as DNA and RNA).
14. Why do most plants have cells with a nucleus, but animals do not (or vice versa)? Explain whether there was an evolutionary advantage for this change in structure over time.)
15. How are genes inherited from parents to offspring, and what changes occur during this process? Also, discuss how these changes affect behavior or appearance within populations over time and what kinds of diseases may be caused by different types of mutations.)

10 Areas of Research in Biology

Here’s a look at 20 areas of research in biology to research about:

1. Agriculture – this area of biology studies how plants and animals can be used to meet human food needs.
2. Botany – the first botanists were those who simply studied plants for their own sake.
3. Cellular Biology – this area studies cells and their components at the molecular level.
4. Developmental Biology – scientists in this field study how living things develop from one stage to another throughout their life cycles.
5. Biochemistry. The study of chemistry is related to living organisms, their functions, and the molecular processes within a living cell.
6. Developmental biology. This is the study of how living organisms grow, develop, produce offspring and eventually die.
7. Cellular biology. A branch of biology that studies the structure and function of cells in the body includes studying how individual cells work together as a unit and how they interact with their environment.
8. Genetics. In the study of heredity, cellular genetics focuses on the genetic material in cells. In contrast, organismic genetics focuses on genetic material related to entire organisms instead of single cells.
9. Microbiology. The study of microscopic life forms; includes bacteria, protists, and fungi, which are all studied by a microbiologist who seeks to understand the origins and behavior patterns of microbes and their relationship to human health and disease development.
10. Immunology. In the study of the immune system, immunologists seek to learn how the immune system functions in its normal condition and when it becomes compromised by illness or disease.
