Prokaryotes are predominantly unicellular organisms that lack a nuclear membrane. Prokaryotes lack all forms of membranous cell components (eg. chloroplasts, mitochondria, etc.). On the other hand, prokaryotes do contain a single circular string of DNA, plasma membranes, primitive cytoskeletons, ribosomes, and vacuoles. Prokaryotes produce asexually, usually by binary fission. They have a rod shaped body that is rounded on the edges. Prokaryotes have a quick metabolism. Prokaryotes can archaea, bacteria, or cyanobacteria. Bacteria can be both beneficial and harmful to us. They can cause several infections that one would not like to have. They could also aid us in digestion and allow for our body to function properly. Prokaryotes are found practically anywhere. The bathroom sink pictured above is a common place for bacteria.
