DIFFUSION
1) Diffusion is the net downward movement of a given substance ions , atoms or molecules , etc . Along the free energy gradients from the place of its higher concentration to an area of its lesser concentration .
2) The diffusion may occur in any medium and the diffusing particles may be solid , liquid or gas .
3) Presence of semipermeable membrane is not required .
OSMOSIS
1) Osmosis is a special type of diffusion of solvent molecules from low concentration of solution to higher concentration of solution , when the two are separated by a semipermeable membrane .
2) The Osmosis occurs in liquid medium and only the Solvent molecules move from one place to another .
3) Presence of semipermeable membrane in between the two solutions is required .
