Osmosis
What is Osmosis?
Osmosis is the spontaneous movement of solvent molecules (usually water) through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration, until equilibrium is reached. Osmosis is driven by the difference in water potential (osmotic pressure difference) across the membrane. It is vital in biological systems for cell hydration, kidney function, and nutrient transport.
