WebOsmosis: Osmosis is the diffusion of water or solvent molecules through a semi-permeable membrane that separates the solution from its solvent. The movement occurs in the direction of high water potential to the low water potential. The process by which the molecules of a solute spread uniformly across a medium is called diffusion, not osmosis. WebOsmotic pressure is the pressure required to stop water from diffusing through a membrane by osmosis. It is determined by the concentration of the solute. Water diffuses into the area of higher concentration from the area of lower concentration.
