Cell A has osmotic potential of -18 bars and pressure potential of 8 b

1.	Cell A has osmotic potential of -18 bars and pressure potential of 8 bars, whereas, cell B has osmotic potential of -14 bars and pressure potential 2 bars. The direction of flow of water will beA. from cell B to cell AB. from cell A to cell BC. no flow of waterD. in both the directions
Answer» Correct Answer - B The water potential is the chemical potential of water, which is equivalent to DPD with negative sign. Therefore, water potential `(Psi_(A))` of cell A= `Psi_(A)=Psi_(s)+Psi_(P)= -18+8= -10` water potential of cell `B(Psi_(B))=Psi_(B)=Psi_(s)=Psi_(P)= -14+2= -12` Since, water moves from higher water potentail to lower potential the flow of water will be from cell A(-10 bars) to cell B (-12 bars).
