Water potential equation

• what 2 opposing forces are plant cells under the influence of?

  • the solute potential, which is due to the solutes in the vacuole and cytoplasm pulling water in - the higher these concentrations, the less likely water is to move out
  • the pressure potential, a force which increases the water potential of the cell and whether water moves in or out
• whats the equation that describes the relationship between the pressures?

  water potential of cell = pressure potential + solute potential
