Cell A has osmotic potential of -18 bars and pressure potential of 8 bars, whereas, cell B has osmotic potential of -14 bars and pressure potential 2 bars. The direction of flow of water will be

Options

A. From cell B to cell A
B. From cell A to cell B
C. No flow of water
D. In both the directions

Answer

B

Explanation

`{:(" Cell A "," Cell B"),(" "Psi_(s) = - 18," "Psi_(s) = - 14),(" "Psi_(p) = 8 ," "Psi_(p) = 2 ),("":. Psi_(w) = Psi_(s) + Psi_(p),"":.Psi_(w)= Psi_(s) +Psi_(p)),(" "= - 18 - 8," "= - 14 + 2 ),(" "= - 10," "= - 12 ):}`
Since water moves from high water potential to low water potential the flow of water will be from A to B
