1. Which beaker(s) contain(s) a solution that is hypertonic to the bag?
2. Which bag above would you predict to show the least change in mass at the end of the experiment?
3. Arrange the beakers above in order of the mass of the bags inside them after the experiment has run for 30 minutes. List the bag that loses the most mass first.
4. Why don't red blood cells within the blood pop in the bloodstream?
5. There are two components to water potential: solute concentration and pressure. How do you think this fact affects the movement of water into and out of cells? For example, can two solutions that differ in their solute concentration be at equilibrium in terms of water movement?
6. Can a solution with a molarity of 0.2 be in equilibrium with a solution with a molarity of 0.4? Explain your reasoning.
7. In beaker B, below, what is the water potential of the distilled water in the beaker, and of the beet core (a sample of tissue containing cells from the beet root)?
8. Which of the following statements is true for the diagrams below?
a. The beet core in beaker A is at equilibrium with the surrounding water.
b. The beet core in beaker B will lose water to the surrounding environment.
c. The beet core in beaker B would be more turgid than the beet core in beaker A.
d. The beet core in beaker A is likely to gain so much water that its cells will rupture.
e. The cells in beet core B are likely to undergo plasmolysis.
