I have an AP Biology test soon, and I cant find this answer anywhere. The book talks about turgor. But it does not talk about water potential at all. Its not even in the index, and what I read online makes no sense to me! Help please!
Thanks!

For starters, turgor is the pressure from the plant cell on the cell walls which makes the cell rigid. Ok..water potential is when water moves from an area of lower solute concentration to an area of higher solute concentration...so it means that if the plant cell(which has a lot of solutes) is placed in maybe distilled water(which has no solutes), the water will move from the distilled water into the plant cell......however, when the plant cell builds enough pressure (from swallowing loads of water) it exerts this pressure on the plant cellwall (meaning it becomes rigid like a swollen penis) so no more water can either enter or leave any of the two mediums.
