Under this system, organisms are classified into three domains and six kingdoms. The domains are Archaea, Bacteria, and Eukarya. The kingdoms are Archaebacteria (ancient bacteria), Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

A domain is the highest grouping of organisms, superseding the level of kingdom in the classical Linnaean system of biological classification.here are three domains, two of which, Eubacteria and Archaea, are composed entirely of prokaryotic organisms; the third domain, Eucarya, encompasses all other (eukaryotic) life forms, including the single-cell and multicellular protists, as well as animals, green plants, and fungi.
