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.
While diffusion involves movement of any chemical from one place to another, osmosis involves movement of only water across a permeable membrane. This makes it clear that it is only water that can undergo osmosis. As such it can be said that osmosis is a special type of diffusion.
