ExplanationA. False. Due to fairly rigid structure, the cell wall has limited flexibility to expandor to diminish in response to modifications of water potential and solute potential.Changes in cell water potential are mainly caused by large changes in turgor pressurewhile changes in ceil volume are little as indicated in the figure.B. False. Plasmolysis begins when turgor pressure of the plant cell disappears. Asshown in figure, the cell volume is reduced approximately 15%. The water potentialand solute potential are both below minus 3.C.True. As the cell volume decreases by 15%, the change in water potential (h'w) is mostly on solute potential (h-s) together with little change in turgor pressure potentialD. True. The backpressure from cell wall is balanced turgor pressure indicate thatplant cell is turgid. At this point, water potential of the cell becomes zero and waterno longer enters or goes out the plant cell.ReferencesLincoln Taiz and Eduardo Zeiger, Plant physiology textbook, fifth Edition 2010.
