Which four kingdoms consist of eukaryotic organisms in the six-kingdom classification?
Protista, Fungi, Plantae and Animalia
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. Prokaryotes are organisms without a well-defined nucleus or cell organelles. All the other kingdoms consist of eukaryotic organisms.
