Detailed explanation-1: -Semipermeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane “chooses” what passes through (size is not a factor).

Detailed explanation-2: -Semipermeable membranes are thin biological sheets of material that allow certain molecules to pass through them more easily than others. The molecules tend to move from areas of high concentration to areas of low concentration-a process called diffusion. An example of a semipermeable membrane is a cell membrane.

Detailed explanation-3: -Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.

Detailed explanation-4: -A semipermeable membrane, also termed a selectively permeable membrane, a partially permeable membrane or a differentially permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized “facilitated diffusion".
