Bacteria and Archaea are made up of prokaryotic cells.


 * Prokaryotic Cells**
 * Prokaryotic cells lack a nucleus. DNA is coiled into nucleoid (which is a region like a nucleus)
 * DNA is in direct contact with the entire cell
 * Plasma membrane encloses cytoplasm around which is a bacterial wall. This wall protects the cell and helps it keep its shape.
 * Prokaryotic cells contain Pili (pilus) which help the bacteria latch on to a surface
 * Prokaryotic flagellum propels cell through water.
