(a) define diffusion as the movement of molecules from a region of their higher concentration to a region of. Osmosis. When the diffusing substance is water, and when the diffusion takes place through a semi permeable membrane the process is called osmosis.. Also the movement of water down a concentration gradient from an area of high solvent concentration (weak solution) to an area of low solvent concentration (stronger solution.).
