Therefore, they do not have a nucleus but instead have a single chromosome—a piece of circular DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall lying outside the plasma membrane. WebKey points: Bacteria can be highly cooperative. Some even form organized structures a lot like a multicellular tissue. Biofilms are surface-attached collections of microorganisms that stick together and exchange nutrients. Some prokaryotes form close associations with plants, animals, or fungi.
