Need for classification

  • There are millions of plants and animals varying greatly in their form, structure and complexity.
  • It is impossible to study all of them individually. To make the study of organisms possible and easier, scientists have divided organisms into different ranks or categories on the basis of similarities and differences.
  • Classification is just like systematically arranged library where we can easily find out the required book, in the same way, if the organisms are arranged according to a system, it makes their study easy.

Some important needs are

  • It is essential to understand the inter-relationship among different groups of organisms.
  • It serves as a base for the development of other biological sciences like biogeography.
  • Various applied biology fields also depend upon exact identification and classification.
