What is biology? Write its sub branches in detail.

Biology is the scientific study of life, encompassing the structure, function, growth, origin, evolution, and distribution of all living organisms. It’s a vast field that explores everything from the smallest molecules to entire ecosystems.

Here are some of its major sub-branches:

1. Botany: The study of plants, including their structure, function, growth, reproduction, and evolution.

2. Zoology: The study of animals, covering their behavior, physiology, evolution, classification, and distribution.

3. Microbiology: The study of microorganisms, such as bacteria, viruses, fungi, and protozoa.

4. Genetics: The study of genes, heredity, and variation in living organisms.

5. Ecology: The study of the interactions between organisms and their environment, including the distribution and abundance of organisms.

6. Physiology: The study of the functions and mechanisms of living organisms and their parts.

7. Anatomy: The study of the structure of living organisms and their parts.

8. Biochemistry: The study of the chemical processes within and relating to living organisms.

9. Cell Biology: The study of cells, their structure, function, and behavior.

10. Evolutionary Biology: The study of the processes that have led to the diversity of life on Earth, including evolution, natural selection, and speciation.

11. Molecular Biology: The study of biology at a molecular level, including the structure, function, and interactions of biological molecules such as DNA, RNA, and proteins.

12. Immunology: The study of the immune system and its responses to pathogens and other foreign substances.

These sub-branches often overlap and are interconnected, reflecting the complex and integrated nature of biological systems.
