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 composition, properties, and form of the cell wall may change during the cell cycle and depend on growth conditions. Cell membrane (also called as plasma membrane, plasmalemma or phospholipids bilayer) is found in all cells. It contains a wide variety of biological molecules (proteins, lipids) which helps the cells in adhesion, ion channel conductance and cell signaling.
