BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Among them only ethylene is found in gaseous form. Hence, the option (c) Ethylene is the correct answer. Additional Information: Ethylene hormone can be produced from almost any part of the plant.

Detailed explanation-2: -Ethylene, often known as the ripening hormone, is a gaseous plant hormone. Ripening fruits, flowers, leaves, and even roots synthesize it. It causes changes in texture, softness, color, and other processes in fruits by triggering a series of events.

Detailed explanation-3: -Ethylene, the Gaseous Plant Hormone.

Detailed explanation-4: -Ethylene gas is a plant hormone that regulates plant growth, development and response to environmental stress. It is produced from leaves, roots, stems, flowers and fruits, and it plays a major role in fruit ripening, flowering and abscission (the natural shedding of leaves, flowers and fruits).

Detailed explanation-5: -Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant species.
