Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which hormone helps the fruit to ripen?
A
Auxin
B
Gibberellin
C
Cytokinins
D
Ethylene
Explanation: 

Detailed explanation-1: -Abscisic acid (ABA) and ethylene are the major regulators of ripening and senescence in both dry and fleshy fruits, as demonstrated by numerous ripening-defective mutants, effects of exogenous hormone application, and transcriptome analyses.

Detailed explanation-2: -Ethylene hormone in plants helps in ripening of fruits. Abscisic acid is known for its inhibiting nature in growth.

Detailed explanation-3: -Ethylene is an important plant hormone. In bananas and many other fruits, production of ethylene surges when the fruit is ready to ripen. This surge triggers the transformation of a hard, green, dull fruit into a tender, gaudy, sweet thing that’s ready-to-eat.

Detailed explanation-4: -Ethylene is a gas and is known as the “fruit-ripening hormone.” Every fruit has a certain level of ethylene production throughout its lifecycle. However, in some fruits, ethylene levels shoot up when the fruit starts ripening.

Detailed explanation-5: -Ethylene is a gaseous hormone found in plants. It is also called as ripening hormone as it induces ripening of fruits. Fruit ripening is accompanied by increase rate of respiration. It inhibits cell division. It is also involved in abscission of leaves, fruits and flowers.
