BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Ethylene is a gaseous plant hormone.

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 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.

Detailed explanation-4: -Ethylene is a volatile compound and the only gaseous plant growth hormone which is mainly found in ripening fruits, flowers and leaves.

Detailed explanation-5: -Complete answer: Ethylene is a gaseous plant hormone (phytohormone) produced by almost all parts of plant but meristematic tissues are considered as active sites for its production.
