  • Water potential
    • Pressure exerted by molecules when colliding with container.
    • Measured in pascals
    • All solutions have negative water potentials
    • Closed system- hydrostatic pressure
    • Cell bursts when can't stand the pressure
      • Cytolsis
      • Cells surrounded by aqueous solution to prevent from bursting
    • Plants
      • Cell wall
      • Turgor pressure increases so entry of water is resisted
      • Water lost from cells by osmosis
