- Anatomy: The study of the structure of living organisms and their parts.
- Botany: The scientific study of plants, including their physiology, structure, genetics, ecology, classification, and economic importance.
- Zoology: The branch of biology that studies the animal kingdom, including animal anatomy, physiology, behavior, genetics, and evolution.
- Microbiology: The study of microorganisms, such as bacteria, viruses, fungi, and protozoa.
- Mycology: The branch of biology concerned with the study of fungi.
- Phycology (Algology): The scientific study of algae.

- Ecology: The study of the relationships between living organisms and their environment.
- Genetics: The study of genes, heredity, and variation in living organisms.
- Physiology: The study of the functions and mechanisms of living organisms and their parts.
- Biochemistry: The study of the chemical processes within and relating to living organisms.
- Evolutionary Biology: The study of the evolutionary processes that have produced the diversity of life on Earth.
- Molecular Biology: The study of the molecular basis of biological activity, including the structure, function, and interactions of biological macromolecules.
