1) Describe the pressure potential at incipient plasmolysis: a) negative b) zero c) positive 2) What happens to the cytoplasm in a cell during incipient plasmolysis? a) Cytoplasm is pushed against cell wall b) No effect on cytoplasm c) Cytoplasm begins to pull away from cell wall d) Cytoplasm is completely pulled away from cell wall 3) What is the relation between the cell's water potential and the water potential of the external solution in incipient plasmolysis? a) The cell's water potential is higher than it is outside of the cell b) The cell's water potential is lower than it is outside of the cell c) The cell's water potential is equal to the external solution 4) When does incipient plasmolysis occur? a) When a plant cell is placed in a hypotonic solution b) When a plant cell is placed in an isotonic solution c) When a plant cell is placed in a hypertonic solution 5) Why is the pressure potential zero in incipient plasmolysis? a) The cell wall does not exert any pressure on cytoplasm b) The cytoplasm does not exert any pressure on cell wall c) The cell wall and cytoplasm exert equal pressure on each other 6) Select the correct diagram for the cells that show evidence of incipient plasmolysis: a) b) c)
