    A plant cell is placed in a solution with a water potential of -0.8 MPa. The cell's initial solute potential is -1.2 MPa and its pressure potential is 0.4 MPa. After equilibration, which of the following statements about the cell's state is MOST accurate?

    A

    The cell will be turgid, with a pressure potential greater than 0.4 MPa.

    B

    The cell will be flaccid, with a pressure potential of zero.

    C

    The cell will be plasmolyzed, with a pressure potential of zero.

    D

    The cell will experience incipient plasmolysis, with a pressure potential slightly above zero.
