Osmosis is the movement of water molecules across a selectively permeable membrane. The net movement of water molecules through a partially permeable membrane from a solution of high water potential to an area of low water potential.
So far, weâve only described the movement of solutes across membranes. However, water (the. solvent) also moves across cell membranes. The movement of water across a selectively permeable. membrane from a region where water is highly concentrated to a region where its concentration is. lower is known as osmosis. Osmosis is a special kind of diffusion, the diffusion of water. In osmosis water always moves by diffusion across a selectively permeable membrane from a. hypotonic solution (low solute concentration, high water conc.) to a hypertonic solution (high solute. concentration, low water conc.).
