Answer:
Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. ... Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.
Explanation:
Examples of osmosis include red blood cells swelling up when exposed to fresh water and plant root hairs taking up water.
Examples of diffusion include perfume filling a whole room and the movement of small molecules across a cell membrane.
