In this lesson, we show a brief introduction to these kingdoms for more information on kingdom please visit a particular lesson on that kingdom. Main Criteria used for this classification are cell structure, thallus organization, mode of nutrients, reproduction and phylogenetic relationship. Besides these major characteristics, he has also given importance to characters of ecological role-played and mode of reproduction. Major criteria on which five-kingdom classification is based Criterion Kingdom Monera Protista Plantae Fungi Animalia Cell type Prokaryotic Eukaryotic Eukaryotic Eukaryotic Eukaryotic…
