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 has different lipid and protein compositions in distinct types of cells and may have therefore specific names for certain cell types: 1  Sarcolemma in myocytes. 2  Oolemma in oocytes. 3  Axolemma in neuronal processes - axons. 4  Historically, the plasma membrane was also referred to as the plasmalemma.
