Cell A has osmotic pot = –15 bars and pressure pot =8 bars and cell B has osmotic pot. =–12 bars and wall pressure 2 bars, what is direction of flow

Always water moves from high water potential to low water potential

Water potential = Osmotic potential + Pressure potential

 For Cell A = -15+8 = -7bars  ; Cell B = -12 +2 = -10 bars

So water molecules move from A$\to$ B
