Increasing the concentration of solutes increases osmotic potential, hence water potential decreases.
A. Agree, because presence of solutes increses osmotic pressure and thus osmotic potential.
C. Agree, because they just represent the same values.
D. Disagree, because it is the decrease in water pressure that decreases osmotic potential.
B. Disagree, because presence of solutes increases osmotic pressure which decreases osmotic potential.

If you place a flaccid plant cell with ΨS = -0.4 MPa in pure water, which of the following will occur? A. Water will not enter the cell because the flaccid cell has solutes and low water potential. B. Water enters the cell because the flaccid cell has solutes and low water potential. C. Water enters the cell because the flaccid cell has solutes and high water potential. D. Water will not enter the cell because the flaccid cell has solutes and high water potential.
