    The three cells A, B & C are joined in a linear manner. Demonstrate the movement of water & direction in these?

    A) \[A\to B\to C~\]            

    B) \[A\leftarrow B\leftarrow C~\]

    C) \[A\to B\leftarrow C~\]               

    D) \[A\leftarrow B\to C~\]

    Correct Answer: C

    Solution :

    \[D.P.D\text{ }=\text{ }O.P-T.P\] water will move from low D.P.D to high D.P.D or \[{{\psi }_{w}}={{\psi }_{s}}+{{\psi }_{p}}\] where \[{{\psi }_{s}}=-O.P.,{{\psi }_{p}}=T.P.\] So \[{{\psi }_{w}}=-DPD\] water will move from high water potential to low water potential.
