Question

Which of the following plant hormones controls fruit ripening?
1. Ethylene
2. Zeatin
3. Auxins
4. Gibberellic acid

Answer 1

Correct Answer - Option 1 : Ethylene

The correct answer is Ethylene.

• Ethylene hormones control fruit ripening.

• ​Ethylene is a plant hormone that affects ripening and rotting in plants. 
• Ethylene is produced in all parts of a plant and diffuses through the plant’s tissue, outside the plant, and travels through the air to affect a totally different plant.

• Zeatin is a type of cytokinin derived from adenine.
  • It occurs in the form of a cis- and a trans-isomer and conjugates.
• Auxin is a hormone involved in cell growth and cell expansion.
• Gibberellic acids are naturally occurring plant hormones that are used as plant growth regulators to stimulate both cell division and elongation.
