Water potential ap biology

Water potential definition

describes the tendency of water to leave one place in favor of another. Moves from high water potential to lower water potential

what is water potential affected by

pressure and the amount of solute

Water potential equation

Water potential equals pressure plus solute

Water potential of pure water in a open container

zero because there is no solute and the pressure in the container is zero

Adding solute ___ the water potential

lowers

dynamic equilibrium

Water potential in water = water potential in plant cell
