explain the basis for grouping organisms into five kingdom
Answers
Answer
The basis of grouping organisms into five kingdoms is as follows:
- Mode and source of nutrition : Organisms are divided into autotrophic and heterotrophic based on mode and source of nutrition.
- Cell wall : Heterotrophs in which the cell wall is present, are under the kingdom fungi.
- Autotrophs in which the cell wall is present, are under the kingdom Plantae.
- Organisms in which the cell wall is absent are taken in the kingdom Animalia.
- Number of cells : These include unicellular and multicellular organisms. Unicellular eukaryotes form the kingdom Protista, and multicellular eukaryotes form the kingdom of Fungi, Plantae, and Animalia.
- Cell Structure : There are two broad categories on the basis of cell structure: eukaryotes and prokaryotes. All prokaryotes are under the kingdom Monera and all others come under other kingdoms.
