(3) How did the various classes of plants and animals come into being?
Ans. ...​

Answer 1

Answer:

Biological classification of plants and animals was first proposed by Aristotle on the basis of simple morphological characters.

Linnaeus later classified all living organisms into two kingdoms – Plantae and Animalia.

Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia.

The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships [evolutionary development and diversification of a species].
