- Botany: The division of biology that deals with the study of plants.
- Cell: The structural and functional unit of life.
- Cell Biology: The study of the structures and functions of cells and cell organelles is called cell biology. This branch also deals with the study of cell division.
- Colony: Group of the unicellular organisms that do not have a division of labor among themselves.
- Community: Populations of different organisms living together in a habitat.
- Embryology: The study of the development of a new individual from a fertilized egg (zygote).
- Entomology: The study of insects.
- Environmental biology: The branch that deals with the study of the interactions between the organisms and their environment.
- Farming: The profession in which different types of farms (e.g. poultry farm, fruit farm, buffalo farm, etc.) are developed and maintained.
- Fisheries: The profession of fish production.
- Forestry: The profession in which the professionals look after natural forests and suggest for planting and growing artificial forests.
- Fossil: Remains or impressions of an organism that existed in the geological past.
- Genetics: The study of inheritance.
- Histology: The microscopic study of tissues.
- Horticulture: The growing of garden plants: the cultivation of fruit and vegetables
- Immunology: The study of the immune system of animals, which defends the body against invading harmful microorganisms.
- Inheritance: The transmission of characters from one generation to the other.
- Macromolecule: The biomolecules with higher molecular weight.
- Microbiology: The division of biology that studies the life of microorganisms
- Micro molecule: The biomolecules with lower molecular weight.
