- B.P – Cytokinins, Q – Auxins
- C.P – Ethylene, Q – Auxins
- D.P – Auxins, Q – Gibberellins
-
2.The hormone that functions as a growth promoter is:
- A.Abscisic acid
- B.Ethylene
- C.Auxin
- D.Both b and c
-
3.Which effect is associated with cytokinin but NOT with auxin?
- A.Stimulates cell division and seed germination.
- B.Promotes stem elongation and phototropism.
- C.Accelerates root growth and fruit development.
- D.Inhibits leaf senescence and delays aging.
-
4.Why are hormones referred to as 'chemical messengers'?
- A.They transmit electrical signals between neurons.
- B.They are released into ducts and transported to target organs.
- C.They are chemicals poured into the bloodstream to regulate body functions.
- D.They break down food molecules during digestion.
-
5.Why does the stem of a plant grow toward light?
- A.Light destroys auxin on the illuminated side, causing uneven growth.
- B.Auxin accumulates on the shaded side, promoting growth and curvature toward light.
- C.Roots secrete a hormone that pulls the stem toward light.
- D.Light directly stimulates cell division on the illuminated side.
