The moment before the plasma membrane began to pull away from the cell wall, the osmotic potential in the bathing solution was -2.00 MPa. The bathing solution was later replaced with deionised water and the cell was given time to reach equilibrium. The plasma membrane was once again pushing against the cell wall.
What is the pressure potential inside the cell now? Explain your answer.

At the beginning the cell was kept inside a hypertonic solution. This caused the shrinkage of cell.
Later the cell is kept inside the hypotonic solution. This leads to the influx of water into the cell. That caused the cell to swell.
The osmotic potential will be negative inside the cell which will be around -2.00 Mpa.
