Sample questions
-
1.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
-
2.Arrange the following terms in the correct logical sequence from the upper surface of a leaf to the stomatal opening: Spongy cells, upper epidermis, stoma, palisade tissue, substomatal space.
- A.Upper epidermis, palisade tissue, spongy cells, substomatal space, stoma.
- B.Upper epidermis, spongy cells, palisade tissue, stoma, substomatal space.
- C.Palisade tissue, upper epidermis, spongy cells, substomatal space, stoma.
- D.Stoma, substomatal space, spongy cells, palisade tissue, upper epidermis.
-
3.Cuticle on leaves:
- A.Prevents photosynthesis.
- B.Reduces transpiration.
- C.Protects leaves from grazing animals.
- D.Gives colour to leaves.
-
4.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.
-
5.Assertion (A): A thick cuticle reduces transpiration by acting as a barrier. Reason (R): Desert plants have large, thin leaves for transpiration. Which of the following is correct?
- A.(A) is true and (R) is false.
- B.(A) is false and (R) is true.
- C.Both (A) and (R) are true and (R) explains (A).
- D.Both (A) and (R) are false.
