  • 3. The Meaning of Biology -Whenever you see “… ology ” or “… logy ” you will be involved in a study of a particular area of, as the stem comes from the Greek “ logos ” which really means the knowledge or study of . -Greek “ bios ” means life , so the general meaning of biology is the study of living things .
  • 4. Fields of Biology Just as the term science is quite general , so too, is biology. The wide field can be broken down into more specific areas. A common division is into: Botany (a study of plants) Zoology (a study of animals) … but there are other divisions. Following is a list of some of the more specific areas of this science which you might come across.
  • 5. 1. Anatomy … Study of the structure of plant and animal organs
  • 6. 2. Bacteriology … Study of microscopic non-green organisms, which may cause disease
  • 7. 3. Cytology … Study of the structure and function of cells
  • 8. 4. Ecology … Study of organisms and their interaction with each other and the environment.
  • 9. 5. Embryology … Study of the early development of organisms
  • 10. 6. Entomology … Study of insects
  • 11. 7. Herpetology … Study of reptiles
  • 12. 8. Histology … Study of the structure of tissues
  • 13. 9. Ichthyology … Study of fish
  • 14. 10. Morphology … Study of the total form or structure of organisms
  • 15. 11. Mycology … Study of fungi
  • 16. 12. Ornithology … Study of birds
  • 17. Study of the life of past geological periods. (ex: dinosaurs) 13. Paleontology …
  • 18. 14. Parasitology … Study of organisms which live and feed on/in the bodies of other organisms
  • 19. 15. Pathology … Study of diseases of organisms
  • 20. 16. Phycology … Study of algae
  • 21. 17. Taxonomy … Study of grouping and classifying organisms
  • 22. 18. Virology … Study of viruses
  • 23. Terminology In biology, many of the terms have been derived from Greek or Latin stems. An example was given when biology was defined and “ology” was explained. A meaning such as this enables a person to at least have a partial idea of what a word might stand for, regardless of what language you speak. “ bios ” + “ ology ” = “ life ” + “ the study ” = the study of life !
