In five kingdom system, the main basis of classification is (a) structure of nucleus (b) mode of nutrition (c) structure of cell wall (d) asexual reproduction.
Option B Whittaker’s system is based on the following three criteria – complexity of cell structure. complexity of the body organization. mode of nutrition. On the basis of these criteria, Whittaker divided organisms into five kingdoms. These five kingdoms are monera, protista, algae, fungi and animalia. In the five kingdom classification all, prokaryotes have been placed in kingdom monera, all unicellular eukaryotes in kingdom protista, fungi (except slime moulds and water moulds) in their separate kingdom while kingdom plantae and kingdom animalia have been retained for multicellular, autotrophic and multicellular holozoic organisms respectively.
