Question

In this diagram when the O.P. of the cell $B$ increases to $18$ , what would be changes with regard to water movement?

• A. Cells $A,C,D$ and $E$ absorb water from $B$
• B. Water diffuses $B$ from outer cell
• C. No movement of water will occur
• D. $B$ absorb of water will occur

Answer 1

Answer: (A)

Cells $A,C,D$ and $E$ absorb water from $B$

In Cells A, C, D, E, the water potential is -6. Whereas in the cell B, it will be -4 if the osmotic potential is 18. Since cell B is at a higher water potential than all other cells, water would flow from cell B to all other cells

So, the correct answer is, 'Cells A,C,D and E absorb water from B'.
