Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.
Diffusion is the movement of a substance from a higher concentration to a lower concentration. Osmosis is the diffusion of water across a semi-permeable membrane. So the dâ¦ifference is that diffusion involves movement of any particles (e.g. solid, liquid, gas) while osmosis can only occur with water.
