Sample questions
-
1.What is the term for the net force with which water is drawn into a cell?
- A.Turgor pressure
- B.Osmotic pressure
- C.Suction pressure
- D.Wall pressure
-
2.What is the name of the pressure responsible for the movement of water molecules across the cortical cells of the root?
- A.Root pressure
- B.Osmotic pressure
- C.Turgor pressure
- D.Capillary pressure
-
3.What is a solution called if its concentration is greater than that of the cell sap?
- A.Hypotonic solution
- B.Isotonic solution
- C.Hypertonic solution
- D.Neutral solution
-
4.Which of the following is NOT an example of a semipermeable membrane?
- A.Egg membrane
- B.Cellophane paper
- C.Parchment paper
- D.Aluminum foil
-
5.To demonstrate that water is conducted upwards through the xylem, a medium-sized young balsam plant is uprooted, washed, and placed in a beaker containing eosin solution (pink) in water (Fig. 4.16). The roots are completely submerged, and the setup is left for 3-4 hours. After this period, the plant is removed, washed, and transverse sections of the roots, stem, and leaves are examined under a microscope. Which labeled part in the diagram (Fig. 4.16) will appear distinctly red due to the eosin stain?
- A.Phloem vessels, as they transport dissolved nutrients throughout the plant.
- B.Xylem vessels, as they conduct water upwards from the roots.
- C.Cortex cells, since they absorb water directly from the solution.
- D.Pith region, as it stores water and nutrients in the stem.
