Question

osmosis is a special kind of diffusion .comment

Answer 1

Answer: The movement of particles from low concentration to high concentration is responsible for the diffusion in liquids and gases. In the case of osmosis the particles move from the low concentration to high concentration through the semi permeable membrane, this happens because of diffusion.

Answer 2

Osmosis only occurs in liquid, that to only in water whereas diffusion occurs in all states of matter. Osmosis requires a selectively permeable membrane whereas diffusion does not. Therefore, osmosis is a special kind of diffusion.
