What will be the direction of movement of water, when solution X having water potential of -12 bars and another solution Z of -8 bars is separated by a semipermeable membrane?

By definition,"Water potential is the potential energy of water per unit volume relative to pure water in reference conditions." Thus, water will move from a higher water potential region to the lower potential region through the semipermeable membrane. In the given two solutions, Z with -8 bars has higher water potential than solution X with -12 bars. Hence, water movement will be from solution Z to X, flowing along the concentration gradient via semi permeable membrane.
