Question

Describe the five kingdom classification of organisms. Write two characteristic features of each kingdom and give one example.

Answer 1

The five kingdom classification of organisms was given by the R.H. Whitteker. This system of classification is the way of grouping organisms on the basis of the structure of the nucleus (prokaryotes and eukaryotes), structure complexity (unicellular and multicellular), mode of nutrition and evolutionary relationship.

The five major kingdoms are:

1. Monera: They are prokaryotic unicellular organisms. They possess a cell wall. This kingdom includes bacteria.

2. Protista: They are eukaryotic unicellular organisms. Some have a cell wall. This kingdom includes euglena.

3. Fungi:: They are eukaryotic multicellular. They are mostly saprophytic. This kingdom includes mucor.

4. Plantae: They are eukaryotic multicellular. They possess cell wall and are autotrophic in nature. This kingdom includes angiosperm.

5. Animalia: They are eukaryotic multicellular. They do not possess a cell wall. This kingdom includes mammals.
