Study Notes

Introduction to Biology

  • Biology is the science of life, derived from the Greek words "bio" meaning 'life' and "logos" meaning 'to study'.
  • The term "biology" was first used by Swedish scientist Carl Linneaus in 1736.
  • Biology has three major divisions: botany (study of plants), zoology (study of animals), and microbiology (study of microorganisms).

Branches of Biology

  • Morphology: studies the form, shape, and structure of organisms.
  • Anatomy: studies the internal structures of organisms.
  • Histology: studies the composition, structure, and functions of plant and animal tissues.
  • Physiology: deals with the functions of different parts of organisms and the activities occurring in them.
  • Embryology: deals with the embryo and the development of an organism from a fertilized egg.
  • Taxonomy: studies the classification of organisms and their scientific naming.
  • Cell Biology or Cytology: studies cells and their organelles.
  • Paleontology: studies fossils of past organisms, including Paleobotany (study of plant fossils) and Paleozoology (study of animal fossils).

Key Concepts

  • In biology, "structure" refers to any part of a living organism that can be seen with the naked eye or with a microscope.
