Diversity in Living Organisms

Question:

Explain the basis for grouping organisms into five kingdoms.

Answer:

The basis for grouping organisms into five kingdoms is:

  • Cell Structure: It has two major cellular structural divisions within living things i.e. prokaryotes and eukaryotes.
  • Number of Cells: It divides into unicellular and multicellular.
  • Mode and source of nutrition: Organisms are divided based on the mode of nutrition i.e. autotrophic and heterotrophic.
  • Phylogenetic Relationship and Body Organisation: Based on body organisation and evolution organisms are divided into simple and complex organisms.
