Diagrams 1 and 2 show how the transverse section through a leaf changes when one solution W to a different solution Y. [Diagram 1 showing a cell in solution W, Diagram 2 showing a cell in solution Y] How has the water potential changed in diagram 2?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Adifference in cells at X in solution Y compared to the same cells in solution W: less negative, difference in solution Y compared to solution W: less negative
Bdifference in cells at X in solution Y compared to the same cells in solution W: less negative, difference in solution Y compared to solution W: more negative
Cdifference in cells at X in solution Y compared to the same cells in solution W: more negative, difference in solution Y compared to solution W: less negative
Ddifference in cells at X in solution Y compared to the same cells in solution W: more negative, difference in solution Y compared to solution W: more negative
✓ Correct answer
A: difference in cells at X in solution Y compared to the same cells in solution W: less negative, difference in solution Y compared to solution W: less negative
