Question

A and B are contiguous cells. A has osmotic pressure (OP) = 10 atm. Turgor pressure (TP) = 7 atm and Diffusion pressure deficit (DPD) = 3atm. B has OP = 8 atm, TP = 3 atm, DPD = 5 atm. The direction taken by the water would be

• A. No movement of water
• B. Equilibrium between the two
• C. Movement of water from A to B
• D. Movement of water from B to A

Answer 1

The correct option is C Movement of water from A to B

Movement of water from A to B since water flows in the direction from low DPD to high DPD. 'A' cell has lower DPD than 'B' so the movement of water from A cell to B cell will be the correct answer.
