The correct option is B from cell A to cell B
Cell A:
Osmotic potential = -18 bars
⇒ Osmotic Pressure (OP) = 18 bars
Pressure potential = 8 bars
⇒ Turgor Pressure (TP) = 8 bars
Therefore, DPD (diffusion pressure deficit) = OP - TP = 18 - 8 = 10 bars.
Cell B:
Osmotic potential = -14 bars
⇒ Osmotic Pressure (OP) = 14 bars
⇒ Turgor Pressure (TP) = 2 bars
Therefore, DPD = OP - TP = 14 - 2 = 12 bars.
Hence, water will move from lower DPD to higher DPD, i.e., from A to B.
