Answer
The final psiS of the cell should be the same as that of the solution, -05MPa. This is still more negative than that of the starting solute potential of the cell, which means that it will be plasmolyzed, with a pressure potential of 0, and a solute potential for the cell of -0.5MPa.
Work Step by Step
This is in parallel with the reasoning for Fig. 37.5 (see caption)--the key is to see that the cell will, as in the example in the figure, be plasmolyzed. This will always make the cell's solute potential equal to that of the surrounding solution.
