Question

Differentiate between selectively permeable and semipermeable membrane.

Answer 1

• The membrane which permits the passage of pure solvent molecules to pass through it and not the solute particles is called semipermeable membrane while the membrane which allows some substances to pass through it more readily than others is known as selectively permeable membrane .
• Moreover, a selectively permeable membrane requires constant energy for its maintenance, whereas a semipermeable membrane does not require constant energy for its maintenance.
