Define osmosis and state how it differs from diffusion.
Original Khojo Papers practice question — not from a past board paper.
Answer
Osmosis is the movement of solvent molecules from a region of higher water potential to one of lower water potential through a semipermeable membrane. Diffusion is the movement of particles of any substance from a region of higher concentration to one of lower, and it needs no membrane.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Osmosis is a special case of diffusion, restricted to the solvent and requiring a semipermeable membrane.
