Six kingdom classification was proposed by Carl Woese. It comprises three domains - Archaebacteria, Bacteria, and Eukarya. These domains are further divided into 6 kingdoms - Archaebacteria, Bacteria, Monera, Protista, Fungi, Plantae, and Animalia. The two kingdoms that consist of prokaryotic organisms are archaebacteria and bacteria.

The three-domain system is a biological classification introduced by Carl Woese, Otto Kandler, and Mark Wheelis in 1990 that divides cellular life forms into three domains, namely Archaea, Bacteria, and Eukaryota.
