Expert Answer:

Osmosis is the diffusion of water or solvent molecules through a semipermeable membrane from a slution of higher water concentration to a solution of lower water concentration until the concentration on both sides is equal.
 
Diffusion is the process in which there is movement of a substance from an area of high concentration of that substance to an area of its lower concentration.
