  13. Botany: The division of biology that deals with the study of plants.
  14. Cell: The structural and functional unit of life.
  15. 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.
  16. Colony: Group of the unicellular organisms that do not have a division of labor among themselves.
  17. Community: Populations of different organisms living together in a habitat.
  18. Embryology: The study of the development of a new individual from a fertilized egg (zygote).
  19. Entomology: The study of insects.
  20. Environmental biology: The branch that deals with the study of the interactions between the organisms and their environment.

  22. Fisheries: The profession of fish production.
  23. Forestry: The profession in which the professionals look after natural forests and suggest for planting and growing artificial forests.
  24. Fossil: Remains or impressions of an organism that existed in the geological past.
  25. Genetics: The study of inheritance.
  26. Histology: The microscopic study of tissues.
  27. Horticulture: The growing of garden plants: the cultivation of fruit and vegetables
  28. Immunology: The study of the immune system of animals, which defends the body against invading harmful microorganisms.
  29. Inheritance: The transmission of characters from one generation to the other.
  30. Macromolecule: The biomolecules with higher molecular weight.
  31. Microbiology: The division of biology that studies the life of microorganisms
  32. Micro molecule: The biomolecules with lower molecular weight.
  33. Microorganism: Any organism (living thing) that cannot be seen with the naked eye. (micro = small)
