Answer: Osmosis
Explanation: Osmosis is a process in which water move from an area of low solute concentration to an area of high solute concentration through a selectively permeable membrane. For osmosis to occur, it must be through a selectively permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
