Osmosis is a special kind of diffusion'. Comment.

Text Solution

Verified by Experts

Yes, the statement is true. In both the cases, there is movement of particles. However, osmosis is restricted to only liquid solutions in which the solvent molecules can pass through the pores of a semi-permeable membrane while solute particles are unable to do so. Diffusion is very common in gases and also takes place in liquids. But no semi-permeable membrane is needed in case of diffusion.
