See Organelle. Prokaryotes have only one lipid bilayer-the cell membrane (also known as the plasma membrane). Many prokaryotes also have a cell wall, but the cell wall is composed of proteins or long chain carbohydrates, not lipids.
Cell Membrane. Nickname: Skin. The cell membrane is on the outside of an animal cell and is found just underneath the cell wall in a plant cell. Similar to the cell wall, it protects the cell and controls what passes in and out of the cell. The membrane is made from lipids and proteins made inside the cell.
