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 is often included in sections about the structure and functions of cell organelles. However, the cell membrane (also known as the plasma membrane) is not within the cell but one of the structures that defines the cell - together with the cell wall in the cases of plant cells and prokaryotic cells. See functions of the cell membrane.
