Prokaryotic cells (like bacteria) are very simple cells. They lack a nucleus, sometimes called the control center of the cell. In prokaryotic (PRO-care-ee-ought-ick) cells, the genetic material or DNA is loose inside and is made of a single loop. The loop is called a plasmid. There are few, if any, organelles, and none are bound by cell membranes. The name prokaryote comes from a Greek word meaning "before nuclei." They are the oldest cells on Earth. These cells divide by simple fission. One cell splits into two identical cells. The germs that make us sick are prokaryotic cells.

The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.
