    If the pressure potential is +0.16 megapascals (MPa) and the osmotic potential is -0.24 megapascals, then the water potential would be:

    A) +0.4 MPa        

    B)        +0.08 MPa

    C) -0.08 MPa        

    D)        +0.16 MPa

    Correct Answer: C

    Solution :

    [c] The water potential is the sum of the osmotic potential (usually negative) and the pressure potential (usually positive), so W.P. = - 0.24 + 0.16 = -0.08 mPa.
