Since the plant cell is maintaining a constant volume in a solution with a ΨS of -0.30 MPa, its Ψ must be equal to -0.30 MPa to balance the solute potential.

To calculate ΨP, we can use the equation Ψ = ΨS + ΨP. Rearranging this equation, we get ΨP = Ψ - ΨS. Plugging in the values we know, we get:

ΨP = (-0.65 MPa) - (-0.30 MPa) = +0.35 MPa

Therefore, the correct answer is C, ΨP of +0.35 MPa.
