Hint: This hormone can be generated from nearly any portion of the plant. It helps in oxygen carrier and controls stem extension and flowering. The synthesis of this hormone can be impeded by carbon dioxide, thus obstructing the procedure of ripening. Across the air, this hormone can also function on other plants.
Complete answer:
The plant hormones, which are also named phytohormones, are crucial to plants as they accomplish several crucial purposes like development, flowering, fruit development, phototropism, stem extension, and so on. There are various kinds of hormones established in a plant like Auxin, Cytokinin, Gibberellin, on. Ethylene, and so on.
All these hormones regulate several purposes in plants but ethylene is the only gaseous plant hormone that results in the development of fruit. It is generally recognized that fresh fruits like bananas, maintained with ripe bananas, grow up overnight. It is because of ethylene discharged from the ripe banana, which facilitates the development of the fruit. It accomplishes so by catalyzing the modification of starch and acids in the raw fruits into sugars, thereby growing them.
Hence the correct answer is option ‘D’.
Note: Ethylene is utilized to expand female flowers in a male plant. Ethylene is also utilized as a synthetic fruit ripener. At the same time, the synthesis of ethylene can be impeded by carbon dioxide, and thus the development can also be regulated. This is occasionally enforced by farmers in large scale production and export of fruits among two different countries.
