- A.increase
- B.decrease
- C.remain steady
- D.slowly increase
-
2.Is the following statement true or false? If false, correct it: 'The escape of plant-sap from the cut surface is called guttation.'
- A.True
- B.False. The escape of plant-sap from the cut surface is called bleeding.
- C.False. The escape of plant-sap from the cut surface is called transpiration.
- D.False. The escape of plant-sap from the cut surface is called respiration.
-
3.________ gives cooling effect in plants.
- a.Transpiration
- b.Evaporation
- c.Translocation
- d.Transportation
-
4.During stomatal transpiration, what causes the stoma to open?
- A.Guard cells losing water and becoming flaccid
- B.Guard cells absorbing water and becoming turgid
- C.Epidermal cells expanding rapidly
- D.Chloroplasts releasing excess oxygen
-
5.Droplets of water may sometimes be seen along the margins of the leaves of a banana plant, growing in wet soil, in the mornings. Are these droplets dew drops, and if not, what process explains their formation?
- A.Yes, these are dew drops formed by condensation of atmospheric moisture on the leaves.
- B.No, these droplets result from guttation, where water is exuded from hydathodes due to root pressure.
- C.No, these droplets are caused by transpiration, where excess water evaporates from leaf surfaces.
- D.Yes, these are dew drops, but they form only on banana plants due to their unique leaf structure.
