A farmer wants to ripen the raw apples in his farm. For this purpose, he keeps the raw apples with the apples that are already ripened.The hormone produced by the ripened apples is
Correct answer: B. Ethylene
- A. Auxin
- B. Ethylene
- C. Cytokinin
- D. Gibberellin
Explanation
The correct answer is Option B, also known as ethylene, is a plant hormone that is crucial in the ripening of fruits. It acts by breaking down cell walls, converting starches to sugars, and decreasing acidity, which collectively contribute to the ripening process. While auxins, cytokinins, and gibberellins have their roles in plant growth and development, they are not directly responsible for the fruit ripening process. Auxins primarily aid in cell elongation, cytokinins in cell division, and gibberellins in growth, but ethene is the key hormone for ripening.

About Plant Growth Regulators
Plant growth regulators are chemical messengers that control growth, development and responses to the environment. The topic covers auxins, gibberellins, cytokinins, abscisic acid and ethylene, including cell elongation, apical dominance, tropisms, seed germination, dormancy, fruit ripening and leaf fall, with growth promoters distinguished from inhibitors.
