Sample questions
-
1.Why are the leaves of xerophytes often modified into spines or reduced in size?
- A.To increase the rate of photosynthesis in low-light conditions.
- B.To minimize water loss by reducing the surface area for transpiration.
- C.To improve the plant's ability to absorb nutrients from the soil.
- D.To protect the plant from being buried by sand in deserts.
-
2.A researcher is investigating various environmental factors that influence the rate of transpiration in plants. Which factor is least likely to affect the rate of transpiration?
- A.Intensity of light
- B.Velocity of wind
- C.Carbon dioxide
- D.Oxygen
-
3.Which of the following best explains why some xerophytes have leaves modified into spines?
- A.Spines increase the surface area for photosynthesis in dry environments.
- B.Spines reduce transpiration by minimizing the surface area exposed to air.
- C.Spines help in absorbing more water from the soil.
- D.Spines prevent the plant from being eaten by increasing its size.
-
4.Where is a stoma exactly located in a plant?
- A.On the epidermis of the leaves.
- B.Inside the xylem vessels.
- C.Along the stem cortex.
- D.Within the root hairs.
-
5.What is a potometer?
- A.An instrument used to measure the rate of transpiration in plants by recording water absorption.
- B.A device that directly measures the amount of water lost from plant leaves.
- C.A tool used to measure the rate of photosynthesis in plants under light conditions.
- D.An apparatus that calculates the root pressure exerted by plants during water uptake.
