Suppose Two Living Plant Cells Are in Contact with Each $\varPsi$

Multiple Choice

Suppose two living plant cells are in contact with each other such that water, but NOT solutes, can pass between them. Also suppose that the cells have the same water potential, and that one cell has $\varPsi$ _p=0.3 MPa and $\varPsi$ _s = -0.5 MPa, while the other cell has $\varPsi$ _s = -0.3 MPa. What is the $\varPsi$ _p of the second cell?

A) $\varPsi$ _p = -0.8 MPa
B) $\varPsi$ _p = 0.1 MPa
C) $\varPsi$ _p = 0.5 MPa
D) $\varPsi$ _p = 0.8 MPa
