    Cell A has\[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W}}}\text{-3}\] bars and cell B has\[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W}}}\text{-8}\] bars. The movement of water will be from

    A)  cell A to cell B

    B)  cell B to cell A

    C)  data insufficient

    D)  water cannot move in negative value of\[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W}}}\]

    Correct Answer: A

    Solution :

    The movement of H2O occurs from high value of              \[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W}}}\]to low value of \[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W }\!\!'\!\!\text{ }}}\] i.e., from less negative        value to more negative value of\[{{\text{ }\!\!\Psi\!\!\text{ }}_{\text{W }\!\!'\!\!\text{ }}}\].
