Movement of water molecules across partially permeable membrane from high water concerntration to region of low water concerntration.
Partially permeable membrane, very small holes in it, only tiny molecules fit through (water) big molecules can't (sucrose).
Water molecules move randomly both ways through membrane.
More water molecules on one side means steady net flow of water in the region with fewer water molecules.
So strong sugar solution gets more dilute, water evens up concerntration.
Type of diffusion, passsive movement of water particles from high water concerntration to area of low water concerntration.
