1. What is water potential?
The potential energy of water per unit volume relative to pure water in reference conditions.
The amount of water present in a solution.
The rate at which water moves across a membrane.
The pressure exerted by water on a cell wall.

Temperature
Presence of dissolved solutes
Atmospheric pressure
Light intensity
3. Water moves from an area of water potential to an area of water potential.
