is bacteria a eukaryote or prokaryote
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.
