Cell A and Cell B are adjacent plant cells. In cell A, ${\mathrm{\psi }}_{\mathrm{S}}$ =− 20 bars,  ${\mathrm{\psi }}_{\mathrm{p}}$ = 8bars. In cell B, ${\mathrm{\psi }}_{\mathrm{s}}$ =−12 bars and ${\mathrm{\psi }}_{\mathrm{p}}$ =2bars. Then, 

Water moves from cell A to cell B

There is no movement of water between cell A and cell B

Water moves from cell B to cell A 

Equal amount of water is simultaneously exchanged between cell A and cell B
