Explain the basis for grouping organisms into five kingdoms.

Explanation

The basis for grouping organisms into five kingdoms are:
`rarr` Complexity of cell structure- There are two broad categories of cell structure. Prokaryotic and Eukaryotic. Thus, two broad groups can be formed, one having prokaryotic cell structure and the other having eukaryotic cell structure. Presence or absence of cell wall is another important characteristic.
`to` Unicellular and multicellular organisms - This characteristic makes a very basic distinction in the body designs of organisms and helps in their broad categorizations.
`to` Cell Wall: Presence and absence of cell wall leads into grouping.
`to` Mode of nutrition - Organisms basically have two types of nutritions- autotrophic who can manufacture their own food and heterotrophic who obtain their food from external environment, i.e., from other organisms). Thus, organisms can be broadly classified into different groups on the basis of their mode of nutrition.
