Question
Chapter 36.1, Problem 2LO
Summary Introduction
To determine: The water potential of a cell.
Introduction: The tendency or ability of water to flow from one region to another through osmosis under the influence of gravitational force and mechanical force is called water potential. In plants, movement of water takes place on the basis of water potential.

Indicate with an arrow which direction water would move through.
What is the physical condition of the cell?
What is the hypothetical concentrations of solvent and solute?
Explain the role of osmosis and that of osmotic pressure in controlling the movement of water across the cell membrane. Compare hypotonic, isotonic, and hypertonic solutions.
Create a diagram that demonstrates the difference between tonicity and osmolarity. Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and use arrows to show the movement of water relative to the cell. Please start with a red blood cell in an isosmotic solution and show what happens to cell shape and water movement when NaCl is added to the solution, or when water is added.
