Detailed explanation-1: -(i) A membrane which permits the passage of pure solvent molecules to pass through it and not the solute particles is called semi-permeable. (ii) A membrane which allows some substances to pass through it more readily than others is known as selectively/differentially permeable.
Detailed explanation-2: -Semi-permeable membranes are very thin layers of material which allow some things to pass through them, but prevent other things from passing through. Cell membranes are an example of semi-permeable membranes.
Detailed explanation-3: -What is the definition of Selective Permeability? The movement of materials across the cell membrane that requires NO ENERGY from the cell. The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
