The Five Kingdom System of classification in organisms was proposed by Robert Whittaker in 1969. The five kingdoms proposed by Robert Whittaker are classified as Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia. Robert Whittaker introduced all the five kingdoms in organisms based on their complexity of cell structures, body structures, mode of obtaining nutrition, and ecological lifestyle.

Classification and Proposal of the Five Kingdom System
Without a proper classification system, it is utterly impossible to identify any living thing due to the sheer number and variety of living things that exist on Earth. Therefore, the classification system was introduced in all fields to make things more orderly and understandable. As a result, organised kingdoms of organisms were categorised.
Robert Whittaker introduced the five kingdom classifications of organisms based on the cell structures, body structures, mode of obtaining nutrition, thallus organization, reproduction, and phylogenetic relationships. The various kingdoms were differentiated on the following basis:
- Kingdom Monera includes prokaryotes.
- Kingdom Protista includes unicellular eukaryotes.
- Kingdom Fungi include fungi.
- Kingdom Plantae includes multicellular eukaryotic plants.
- Kingdom Animalia includes multicellular animals.
