Classification of Kingdoms

R.H. Whittaker suggested five types of kingdoms namely Monera, Protista, Fungi, Plantae, and Animalia. The main characteristics considered by him for the classification are cell structure, body organization, mode of nutrition, reproduction, and phylogenetic relationship.

  • Monera: The main members of this category are bacteria.
  • Protista: In this category, all single-celled eukaryotes are placed.
  • Fungi: This constitutes heterotrophic organisms.
  • Plantae: All eukaryotic chlorophyll-containing organisms are incorporated into the Plantae kingdom.
  • Animalia: This category comprises all heterotrophic eukaryotic organisms that do not have cell walls and are multicellular.
