Answer 1

R.H. Whittaker proposed the Five Kingdom Classification. In his system of classification:

• Kingdom Monera includes all the unicellular prokaryotes.
• Kingdom Protista includes the unicellular eukaryotes, which are primarily aquatic and they have a well-defined nucleus and various other cell organelles.
• Kingdom Fungi constitutes a unique kingdom of heterotrophic organisms, which show a great diversity in morphology and habitat.
• Kingdom Plantae includes different forms of plants. It is further categorised into algae, bryophytes, pteridophytes, gymnosperms and angiosperms.
• Kingdom Animalia includes all the animals categorised into distinct phylum.
