'The passage of water from an area of high water potential to an area of low water potential through a partially permeable membrane'

  • Water potential: the pressure created by water molecules. At 25c and 100kPA, pure water has a water potential of 0.
  • The addition of a solute to pure water will lower its water potential.
  • More solute added=more negative water potential.
  • A solution of lower concentration has fewer solute molecules and a higher…
