Osmosis is the movement of water and diffusion is the movement of everything else.

Detailed explanation-1: -In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
Detailed explanation-2: -Osmosis can only function in a liquid medium, but diffusion can occur in all three mediums (solid, liquid and gas). Furthermore, osmosis requires a semi-permeable membrane, while diffusion does not. The intake of water in plants is an example of osmosis.
Detailed explanation-3: -Hint: Diffusion is the movement of any substance from a region of its higher concentration to a region of lower concentration. It occurs in all directions. Osmosis is the movement of water or any other solvent from a region of low solute concentration to a region of high solute concentration.
