CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
Ethylene
Gaseous Hormone Identification
Plant hormones, also known as phytohormones, regulate plant growth and development. Among the common plant hormones, one exists primarily in a gaseous state.
The options provided are:
- Auxin
- Gibberellin
- Ethylene
- Cytokinin
Identifying the Gaseous Hormone
Ethylene is the only plant hormone that is a gas at room temperature and atmospheric pressure. It is involved in processes like fruit ripening, senescence, and abscission.
Auxins, Gibberellins, and Cytokinins are typically found and function in non-gaseous forms (e.g., liquids or solids). Therefore, Ethylene is the correct choice for the gaseous hormone.
