Question

Philoid · Accepted Answer

The basis for grouping organisms into five kingdoms are:

1) Complexity of cell structure: It has two major cellular divisions within living things: Prokaryotic and Eukaryotic. Thus, two broad groups can be formed- one having prokaryotic cell structure and the other having eukaryotic cell structure.

2) Number of cells: It divides living organisms into unicellular and multicellular.

3) Mode of nutrition: Organisms basically have two types nutritions- autotrophic and heterotrophic. Thus, organisms can be broadly classified into different groups on the basis of their mode of nutrition.

4) Phylogenetic relationship: Based on body organization and evolution, organisms are divided into simple and complex organisms.
