The third domain is Eukaryota, whose members are called eukaryotes. Many eukaryotes are unicellular, and many are multicellular. Whether consisting of one cell or many, all Eukaryotic cells are complex, having a nucleus and other complex organelles.
In contrast, prokaryotes are organisms, such as bacteria and archaea, that lack nuclei and other complex cell structures. Eukaryotes share a common origin, and are often treated formally as a superkingdom, empire, or domain. In the domain system, eukaryotes have more in common with archaean prokaryotes than bacterial prokaryotes.
