Question

Which of the following statements regarding plant hormones is incorrect ?

• A. Gibberellins stimulate cell enlargement
• B. Cytokinins promote cell division
• C. Abscisic acid generally promotes growth
• D. The growth of plants in nature is probably regulated by a combination of growth- stimulating and growth-inhibiting hormones

Answer 1

The correct option is C Abscisic acid generally promotes growth

Growth of plants is regulated by a combination of growth-stimulating and growth-inhibiting hormones. ABA (abscisic acid) acts as a general plant growth inhibitor and an inhibitor of plant metabolism.

Gibberellins stimulate cell enlargement. Natural cytokinins are synthesised in regions where rapid cell division occurs.

So, the correct answer is "option B"
