II. SHORT ESSAY (10 points total @ 5 points/question). Answer each of the questions in the space provided (you can use the back of the page if necessary). (1) Briefly describe how the concept of water potential is utilized to predict the direction of water flow. What is the water potential of pure water? How does the water potential of a plant cell relate to the cell solute potential and pressure potential (i.e. mathematical relationship)?
