Sample questions
-
1.Herbaceous plants growing in well-watered soil are found to wilt on a hot day. Which of the following best explains this phenomenon?
- A.The rate of photosynthesis exceeds the rate of respiration, causing energy imbalance.
- B.The rate of transpiration is greater than the rate of water absorption from the soil.
- C.The soil water becomes too warm, damaging the plant roots directly.
- D.The plants lose minerals faster than they can absorb them, leading to deficiency.
-
2.Exudation of sap from injured parts.
- A.Guttation
- B.Secretion
- C.Bleeding
- D.Active transport
-
3.Does lower atmospheric pressure increase or decrease the rate of transpiration?
- A.Increases the rate of transpiration
- B.Decreases the rate of transpiration
- C.Has no effect on transpiration
- D.Stops transpiration completely
-
4.Determine whether the following statement is true or false: The upper surface of the leaves transpires more.
- A.True
- B.False, the lower surface transpires more
- C.False, both surfaces transpire equally
- D.False, only the edges transpire
-
5.In any experiment to demonstrate transpiration, the leaf must remain attached to its parent plant. Why is this necessary?
- A.To ensure the leaf receives continuous water supply through the xylem vessels for transpiration.
- B.To prevent the leaf from drying out due to exposure to air.
- C.To allow the leaf to absorb nutrients directly from the soil.
- D.To maintain the leaf's color and prevent it from turning brown.
