WebOct 25, 2024 · Osmosis is the movement of water through a semipermeable membrane according to the waterʼs concentration gradient across the membrane, which is inversely proportional to the solute's concentration. WebOsmosis is much like simple diffusion but it specifically describes the movement of water (not the solute) across a selectively permeable membrane until there is an equal concentration of water and solute on both sides of the membrane. Simple diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy .
