Question

Which of the following plant hormone promotes cell division?

• A. Auxin
• B. Cytokinin
• C. Ethylene
• D. Gibberellin

Answer 1

The correct option is B Cytokinin

A. Auxin promotes cell elongation, apical dominance, root initiation, parthenocarpy and prevents abscission.

B. Cytokinin promotes cell division and organ formation, delays senescence, promotes lateral bud development, enhances cell expansion in cotyledon leaves, promotes chloroplast development.

C. Ethylene is the fruit ripening hormone and induces ripening in fruit.

D. Gibberellin promotes stem elongation, seed germination, breaks dormancy, promotes elongation of internodes and induces parthenocarpy.

So, the correct answer is 'Cytokinin'.
