Quizplus · Accepted Answer

The plant cell maintains a constant volume, indicating that the water potential (Ψ) inside the cell equals the water potential of the surrounding solution. The solution has a Ψ_S of -0.30 MPa, so the cell's Ψ must also be -0.30 MPa. Given the cell's Ψ_S is -0.65 MPa, the pressure potential (Ψ_P) must be +0.35 MPa to balance the solute potential and achieve a total Ψ of -0.30 MPa.
