Semipermeable Membrane
What is Semipermeable Membrane?
A semipermeable membrane is a membrane that allows the passage of certain molecules or ions (typically the solvent) while blocking others (solute particles), based on size, charge, or chemical affinity. In osmosis, water passes through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. Biological cell membranes are selectively permeable and regulate the passage of water, ions, and nutrients in and out of cells.
