Question

Select from the following a plant hormone which promotes cell division.

• A. Gibberellins
• B. Auxins
• C. Abscissic Acid
• D. Cytokinins

Answer 1

The Correct Option is D

Step 1: Understanding plant hormones:
Plant hormones are chemical substances that regulate growth, development, and responses to stimuli in plants. Different hormones play specific roles in various processes such as growth, flowering, fruiting, and responses to environmental factors.

Step 2: Identifying the hormone that promotes cell division:
Among the different plant hormones, one of the key hormones that promote cell division is:

- Auxins: These hormones primarily promote cell elongation, not division.
- Gibberellins: They promote cell elongation and are involved in processes like seed germination and stem elongation.
- Cytokinins: These hormones specifically promote cell division. They are involved in stimulating the growth of lateral buds and the development of new tissues.
- Abscisic acid: This hormone generally acts in stress responses and inhibits growth.

Step 3: Conclusion:
The plant hormone that promotes cell division is

Cytokinins
