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.
The cell membrane (also known as theplasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from theoutside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
