| Cell | Osmotic Potential (MPa) | Pressure Potential (MPa) |
| A | - 0.95 | 0.40 |
| B | - 0.75 | 0.40 |
| C | - 085 | 0.25 |
| D | - 0.65 | 0.25 |
A) \[D\to B\to C\to A\]
B) \[B\to C\to D\to A\]
C) \[C\to B\to A\to D\]
D) \[B\to D\to A\to C\]
Correct Answer: D
Solution :
Water Potential = Osmotic Potential + Pressure Potential \[\Psi ={{\Psi }_{o}}+{{\Psi }_{p}}\] \[\therefore {{\Psi }_{A}}=-0.95-0.4=-0.55MPa\] \[{{\Psi }_{B}}=-0.75-0.40=-0.35MPa\] \[{{\Psi }_{C}}=-0.85-0.25=-0.60MPa\] \[{{\Psi }_{D}}=-0.65-0.25=-0.40MPa\] The correct sequence of cells, which shows the path of water movement between them is \[B\to D\to A\to C\]
