<P> A prokaryote is a unicellular organism that lacks a membrane - bound nucleus ( karyon ) , mitochondria , or any other membrane - bound organelle . The word prokaryote comes from the Greek πρό ( pro ) `` before '' and κάρυον ( karyon ) `` nut or kernel '' . Prokaryotes can be divided into two domains , archaea and bacteria . In contrast , species with nuclei and organelles are placed in the domain Eukaryota . </P>
