Here are the different branches of biology (or divisions of biology) and their definitions & their related resources.

Anatomy

Anatomy is the branch of biology that deals with the study of the structure of organisms and their parts.

Biochemistry

Biochemistry is the branch of biology concerned with the chemical and physiochemical processes that occur within living organisms.

Biophysics

Biophysics is the science of the application of the laws of physics to biological phenomena.

Biotechnology

Biotechnology is the exploitation of biological processes such as genetic manipulation of micro-organisms for the production of antibiotics, hormones, etc.

Cell Biology

Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life.

Ecology

Ecology is the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
