Answer 1

Answer:

Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by Osmosis—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

Answer 2

However it does not allows the passage of solute molecules. Hence, semipermeable membrane is used during osmosis and reverse osmosis process. For example, desalination of water requires use of semipermeable membrane.
