  • Botany studies different types of plants.
  • Ecology explores the way living organisms exist in their specific environment.
  • Biochemistry examines the material that forms living things.

  • Physiology studies the functions of living organisms.

  • Evolutionary biology studies the origin and modifications during a live cycle.
  • Molecular biology examines different types of biological molecules.

Therefore, it is impossible to study genetics, for example, if you are unaware of the basic aspects of evolutionary biology, physiology or cellular biology. Mind that one cannot handle the botany issues properly if they know nothing about biochemistry.
