Question

Name the membrane that allows solvent molecules to pass through it.

• A. Semi-permeable membrane
• B. Selectively permeable membrane
• C. Impermeable membrane
• D. Both A and B

Answer 1

The correct option is D

Both A and B

Membranes which does not allow any substance to pass through them are called impermeable. Semi- permeable membranes allow only solvent molecules to pass through them. Selectively permeable membranes allow solvent and selective solute molecules to pass through them. Hence, both semi- permeable as well as selectively permeable membranes allow solvent molecules to pass through them.
