A semipermeable membrane is a membrane that allows only the flow of solvent molecules but not solute molecules. During the process of osmosis and reverse osmosis, the semipermeable membranes allow the movement of solvent molecules. Examples of semipermeable membranes are cellulose acetate and phospholipid bilayer in biological cells.
