A prokaryote is an organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria and archaea are the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.

Protists belong to the eukaryotes, but form an extremely diverse group that includes everything except animals, plants and fungi.
