Question

Coconut milk factor is:

• A. An auxin
• B. A gibberellin
• C. Abscisic acid
• D. Cytokinin

Answer 1

The Correct Option is D

The correct answer to the question "Coconut milk factor is:" is Cytokinin. Here's why:

1. Definition of Cytokinins:
   • Cytokinins are a class of plant hormones that promote cell division (cytokinesis) in plant roots and shoots.
   • They are involved in various plant processes, including cell growth and differentiation, apical dominance, leaf senescence, and more.
2. The Role of Coconut Milk:
   • Coconut milk contains natural compounds crucial for plant tissue culture. It was one of the first natural sources recognized to have cytokinin activity.
   • In historical studies, it helped in promoting the growth of plant tissues in culture, which led researchers to identify the presence of cytokinins in coconut milk.
3. Reasoning for the Options:
   • An auxin: Auxins are another type of plant hormone that stimulates cell elongation, but they are not primarily found in coconut milk.
   • A gibberellin: Gibberellins are hormones that promote seed germination and growth but are not the primary factor in coconut milk.
   • Abscisic acid: This hormone is involved in stress responses and seed dormancy, and has no relation to coconut milk's functions.
   • Cytokinin: As established, cytokinins are the correct factor found in coconut milk, promoting cell division and growth.
4. Conclusion: Due to its cell division-promoting properties, cytokinin as a component of coconut milk is rightly termed the "coconut milk factor."
