Question

The solute potential of a plant cell is -10 bar, and its pressure potential is 3. The plant cell is placed into a solution with a water potential of -10 bar.
What is the water potential of the cell, and in which way will water move?

Answer 1

The water potential of the cell would be -7 bar and thus, water will move from the cell to the surrounding solution.

Recall that:

Water potential = pressure potential + solute potential

For the plant cell, solute potential = -10, pressure potential = 3

Water potential of the cell = 3-10

                                          = -7 bar

The water potential of the cell is -7 bar while that of the surrounding solution is -10 bar. Thus, the cell has a higher water potential than the surrounding solution.

Recall that water usually moves from the region of high to the region of low water potential. Therefore, water will move from the cell to the surrounding solution.
