31. A recent levy has been breached, causing flood- ing in a local community with saltwater. A local farmer is trying to determine if his crops can survive the flooding. The saltwater has a water potential of -8.73 MPa . The farmer's crops have a molar concentration of 0.25 M with a pres- sure potential of -1.0 MPa at $$\(27^{\circ} \mathrm{C}\)$$. What will happen to the crops?
A.
The crops will maintain turgid pressure due to the crop's water potential being -7.23 MPa$ and the saltwater being -8.73 MPa .
B.
The crops will become flaccid and eventu- ally die due to the crop's water potential being -7.23 MPa and the saltwater being -8.73 MPa .
C.
The pressure potential of the plant will cause the crops to gain water from the flooding saltwater.
D.
The pressure potential of the plant will push the sugar out of the crops into the flooding saltwater.
