Prokaryotes do not have a real formed core (Greek: karyon – core). Their DNA is a single ring molecule, freely located in the cytoplasm and not surrounded by a membrane. Prokaryotic cells lack plastids, mitochondria, the endoplasmic reticulum, Golgi apparatus, and Lysosomes. Both prokaryotes and eukaryotes have ribosomes (larger ones in nuclear ones). The flagellum of the prokaryotic cell is thinner and works on a different principle than the flagellum of eukaryotes. Eukaryotic organisms are fungi, plants, animals – unicellular and multicellular; prokaryotes – bacteria and blue-green algae (cyanobacteria).
