The 5 Kingdom Classification which will be followed on this Wiki

is a taxonomic rank in Biology which is considered to be the highest rank under the 5 Kingdom Classification System. 

Kingdom Classification Edit

Kingdom Classification has been continously modified over the last two centuries, with different taxonomists putting different groups under it. Charles Linneus used a 2 Kingdom Classification System. Robert Whittaker later introduced a 5 Kingdom Classification. Woese introduced a Six Kingdom Classification, and recently in 2015 a Seven Kingdom Classification was introduced by Cavalier-Smith.

5 Kingdom Classification (Whittaker)Edit

The five kingdoms introduced under Robert Whittaker (1969) were as follows:

  • Monera (Prokaryotic, Unicellular, Hetero/Autotrophic)
  • Protista (Eukaryotic, Unicellular, Hetero/Autotrophic)
  • Fungi (Eukaryotic, Multicellular, Saprotrophic)
  • Plantae (Eukaryotic, Multicellular, Autotrophic)
  • Animalia (Eukaryotic, Multicellular, Heterotrophic)

In 1977, Carl Woese broke up Monera into Archaebacteria and Eubacteria.

7 Kingdom ClassificationEdit

Modern 7 kingdom classification by Cavalier-Smith is as follows:


  • Viruses have not been fitted into any kingdom as they only replicate inside a living "host" cell.
