Hello dear student,

I am hoping you are asking about the biological classification of the kingdom. So many classifications are proposed by different scientists , but the one we consider is by Whittaker. He proposed 5 kingdom classification.  That is Monera ,protista ,fungi ,plantae and animalia. This classification is based on these characteristics which are cell structure, body organisation, mode of reproduction, nutrition and phylogenetic relationship.

I hope this is helpful

Thank you

Whittaker proposed an elaborate five kingdom classification Monera, Protista,Fungi,PlantaeandAnimalia. The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.
