Question

Quizplus · Accepted Answer

Osmosis is a specific type of diffusion that involves the movement of water molecules through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. Diffusion, more broadly, refers to the movement of molecules (not just water) from an area of high concentration to an area of low concentration, and it does not necessarily require a semipermeable membrane.
