Question

Hormone that stops cell division in plants is called

• A. Auxin
• B. Ethylene
• C. Cytokinin
• D. Abscisic acid

Hint:

Cytokinin promotes cell division, while Abscisic acid inhibits it.

Answer 1

The Correct Option is D

Step 1: Plant Hormones and Their Roles:
Auxin → promotes cell elongation.
Cytokinin → promotes cell division.
Ethylene → helps in ripening of fruits.
Abscisic acid (ABA) → inhibits growth and stops cell division.
Step 2: Function of Abscisic Acid:
ABA is known as the stress hormone in plants.
It prevents cell division and growth during unfavorable conditions (e.g., drought).
It also induces stomatal closure to prevent water loss.
Step 3: Final Answer:
The hormone that stops cell division in plants is Abscisic acid.
