The value for Ψ in root tissue was found to be - 0.15MPa. If you take the root tissue and place it in a 0.1M sucrose solution (Ψ = -0.23). Which on the following should occur? Select one:
a. Sucrose will be taken up by the root.
b. The root will synthesize sucrose to match the outside solution.
c. The root will lose water to the outside solution.
d. The root will take up both water and sucrose.
Homework Answers
Answer: c. The root will lose water to the outside solution.
The highest water potential is zero (0), found in pure water. Water moves from higher water potential to lower water potential. As solute concentration increases, the water potential decreases. The root water potentia is more (-0.15 MPa) than the sucrose solution (-0.23MPa). So that water mover from roots to oustide sucrose solution. It means that the root will lose water to the outside solution.

Take three cuvettes from the Containers shelf and place them onto the workbench. Take an Erlenmeyer flask from the Containers shelf and place it onto the workbench. There is a solution on the Materials shelf labeled 2% starch. This has a starch concentration of 1 mg/ml. In the Erlenmeyer flask, you should create 100 mL of a new starch solution that is 1/400th of the stock solution using water as the filler. How much starch and water should you add?...
