Suppose a living plant cell has $\varPsi$_p = 0.4 MPa and $\varPsi$_s = -0.5 MPa. Suppose also that the plant cell is placed into a beaker filled with a solution for which $\varPsi$=$\varPsi$_s=-0.9 MPa. What will the cell then do?

Question

Quizplus · Accepted Answer

Water moves from areas of higher water potential to areas of lower water potential. Since the cell's water potential (0.4 MPa) is higher than the solution's water potential (-0.9 MPa), water will move out of the cell to the solution until their water potentials are equal.
