Prokaryote (health)


Prokaryotes are unicellular (in rare cases, multicellular) organisms without a nucleus. The name prokaryote comes from the Greek pros meaning before and karyon meaning nut, referring to the nucleus. This is in contrast to eukaryotes, organisms that have cell nuclei and may be variously unicellular or multicellular. The difference between the structure of prokaryotes and eukaryotes is so great that it is considered to be the most important distinction among groups of organisms.
