Diffusion of water through a differentially permeable membrane is called

osmosis

Explanation:

another kind of diffusion. - diffusion of water through a differentially permeable membrane from a region of high concentration to a region where the concentration is lower. osmotic pressure. of a solution is a measure of its tendency to draw water molecules into it by osmosis.

Osmosis. The direction of water movement across the cell membrane depends on the concentration of free water.
