SUMMARY
Diffusion refers to the process where particles spread from an area of higher concentration to an area of lower concentration, while osmosis specifically describes the movement of water molecules through a selectively permeable membrane. Osmosis can be considered a type of diffusion, but diffusion does not involve the selective permeability characteristic of osmosis. Key distinctions include that osmosis is limited to solvent movement, primarily water, whereas diffusion applies to solute particles in general.
