Prokaryote

Prokaryote
Wikipedia.org

The prokaryotes (singular pronounced /proʊˈkæriət/) are a group of organisms that lack a cell nucleus (= karyon), or any other membrane-bound organelles. They differ from the eukaryotes, which have a cell nucleus. Most are unicellular, but a few prokaryotes such as myxobacteria have multicellular stages in their life cycles.[1] The word prokaryote comes from the Greek πρό- (pro-) "before" + καρυόν (karyon) "nut or kernel", referring to the cell nucleus, + suffix -ώτης (-ōtēs) (pl. -ώτες (-ōtes)). It is also spelled "procaryote".[2]
