| Cell | Osmotic Potential (MPa) | Pressure Potential (MPa) |
| A | -0.87 | 0.44 |
| B | -0.92 | 0.34 |
| C | -0.68 | 0.27 |
A) A, B, C
B) A, C, B
C) C, A, B
D) B, C, A
Correct Answer: C
Solution :
Water potentials of the given cells are \[\psi ={{\psi }_{S}}+{{\psi }_{P}}\] \[A=-0.87+0.44=-0.43\] \[B=-\text{ }0.92+0.34=-0.58\] \[C=-0.68+0.27=-0.41\] As water moves from greater water potential to less, root hair, root cortical and leaf mesophyll cells are C, A, B respectively.
