Two plant cells, A and B, are connected by plasmodesmata. Cell A contains 0.30 mol L⁻¹ sucrose, cell B contains 0.10 mol L⁻¹ sucrose. The temperature is 25 °C (298 K). The pressure potential (ψp) of cell A is +0.4 MPa and that of cell B is -0.2 MPa. Using ψ = ψs + ψp and ψs = -i C R T (i = 1, C = 0.0831 L·MPa·K⁻¹·mol⁻¹), determine the direction of net water movement between the cells.

Answer Options

A. From cell A into cell B
B. No net water movement
Correct Answer C. From cell B into cell A
D. Water moves equally in both directions (no net flow)
Correct Answer
C
Correct Option:
From cell B into cell A
