Challenge Problems
Push your limits with advanced challenges
A plant cell has a solute potential of -0.7 MPa and a pressure potential of 0.3 MPa. Calculate the total water potential and predict whether the cell will gain or lose water if placed in a solution with a water potential of -0.5 MPa.
💡 Hint: First calculate Ψ then compare it to the external solution.
If the solute potential of a cell is -2.5 MPa and the pressure potential is 1.0 MPa, describe how this influences the cell's osmotic behavior when placed in pure water.
💡 Hint: Think about how water interacts with different potentials.
