Question

Write the difference between two Kingdom and five Kingdom system

Answer 1

Classification of organisms into groups is mostly a matter of convenience. Some people have tried to classify all biota into homogenous groups based on a theory of descent, however this has been shown to be unrealistic. The rank of various groups also shifts from time to time depending on the current view. The two kingdom approach: Eukaryota and Prokaryota has been raised to superkingdom, also called domains, The Prokaryota has been split into Bacteria and Archaea to produce three domains. The Eukaryota had the subkingdoms raised to kingdom status (again): Protista, Plantae, Fungi, Animalia. A very old system counted the five as Prokaryota (Bacteria), Protista, Plantae, Fungi, Animalia. There are other systems as well.
