- C.It is the loss of water in the form of water vapour from the aerial parts of the plant.
- D.It is the loss of water in the form of water vapour from all parts of the plant.
-
2.What is the primary reason for xerophytes having leaves modified into spines?
- A.To enhance the plant's ability to absorb sunlight for photosynthesis.
- B.To reduce water loss by decreasing the surface area for transpiration.
- C.To increase the plant's resistance to strong winds.
- D.To attract pollinators in dry environments.
-
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: Transpiration takes place only in green plants.
- A.True
- B.False, it occurs in all plants
- C.False, it occurs only in non-green plants
- D.False, it occurs in both plants and animals
-
5.Why does a well-watered potted plant show wilting of leaves on a hot sunny day?
- A.The roots absorb too much water, causing leaf cells to burst.
- B.The rate of transpiration exceeds the rate of water absorption by roots.
- C.The plant undergoes dormancy due to excessive heat.
- D.The leaves lose chlorophyll due to intense sunlight.
