name two distinct groups of prokaryotes
The word prokaryote comes from the Greek ÏÏÏ- (pro -) before and ÎºÎ±ÏÏÏÎ½ (karyon)  nut or kernel . Prokaryotes can be divided into two domains, Archaea and Bacteria, with the remainder of species, called eukaryotes, in the third domain Eukaryota.owever, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes. This is one of many pieces of evidence that mitochondria and chloroplasts are themselves descended from free-living bacteria.
