What is the "FIVE KINGDOM CLASSIFICATION OF LIVING ORGANISMS" ?

The diversity of organisms we see in day today life is the outcome of billion years of evolutionary process. For proper and systematic study, these living organisms should be grouped on the basis of certain criteria.

Robert. H. Whittaker (1969) proposed the Five Kingdom Classification of the living organisms. He classified the living organisms on the basis of cell structure, cell wall, mode of nutrition and mode of reproduction into five kingdoms.
