  • Osmosis
    • osmosis is the movement of water across a partially permeable membrane
    • as with diffusion the movement of particles is random and requires no energy
    • the water moves from an area of high water concentration (a dilute solution) to an area of low water concentration (a concentrated solution)
    • osmosis only refers to the diffusion of water molecules
