Question

Match the LIST-I with LIST-II. LIST-I: A. Auxin, B. Abscisic Acid, C. Ethylene, D. Cytokinin. LIST-II: I. Cell Division, II. Fruit Ripening, III. Cell elongation, IV. Growth inhibitor.

• A. A-III, B-II, C-I, D-IV
• B. A-IV, B-II, C-I, D-III
• C. A-IV, B-III, C-II, D-I
• D. A-III, B-IV, C-II, D-I

Hint:

Auxin promotes elongation, cytokinin promotes division, ethylene promotes ripening and ABA inhibits growth.

Answer 1

The Correct Option is D

Concept:
Plant hormones regulate growth and development in plants.

Step 1: Auxin.
Auxin mainly promotes cell elongation. \[ A\rightarrow III \]

Step 2: Abscisic acid.
Abscisic acid is a growth inhibitor and is also involved in stress responses. \[ B\rightarrow IV \]

Step 3: Ethylene.
Ethylene promotes fruit ripening. \[ C\rightarrow II \]

Step 4: Cytokinin.
Cytokinin promotes cell division. \[ D\rightarrow I \] Therefore: \[ A-III,\ B-IV,\ C-II,\ D-I \] \[ \therefore \text{Correct Answer is (D)} \]
