AP BIO 2. The plant cell from question #1 is placed in a beaker of sugar water with ΨS = -4.0 bars. In
which direction will the net flow of water be?

3. The original cell from question # 1 is placed in a beaker of sugar water with ΨS = -0.15 MPa
(megapascals). We know that 1 MPa = 10 bars. In which direction will the net flow of water be?

4. The value for Ψ in root tissue was found to be -3.3 bars. If you place the root tissue in a 0.1 M
solution of sucrose at 20°C in an open beaker, what is the Ψ of the solution, and in which
direction would the net flow of water be?

5. NaCl dissociates into 2 particles in water: Na+ and Cl-. If the solution in question 4 contained 0.1
M NaCl instead of 0.1 M sucrose, what is the Ψ of the solution, and in which direction would the
net flow of water be?
