2. transpiration
capillary action, by adhesion and cohesion, water drops are moved up and out the leaves.

4. Water potential The potential energy per unit volume.
Tendency of water to move from one area to another.
We know water moves from an area of _____
Formula:
The more negative the water potential the more chance of water moving in.
