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.
Most textbooks are likely to use the two terms interchangeably (as the outer membrane surrounding living cells), but you might find sources that say that the plasma membrane is the outer membrane (surrounding the cytoplasm), but both the plasma membrane and membranes surrounding organelles inside the cell are called cell membranes.
