the pressure necessitated to hinder the movement of water by way of a partially permeable membrane from a region of low concentration of solution to a region of higher concentration. It stems from the abrupt moving of molecules occurring whenever varied concentrations are divided by a partially permeable membrane.

OSMOTIC PRESSURE: "Osmotic pressure is necessary to keep water out of membranes with lesser-concentrated solutes."
