A store placed a large basket of fruit containing oranges and unripe bananas by the cash register. There were too many bananas to fit in the basket, so they put the rest in the back room. The next day, the bananas in the basket had ripened, but the ones in the back room had not. What is the most likely explanation?

The heat in the store had accelerated the ripening process.

The cytokinins in the oranges diffused into the bananas where the two fruits touched each other and triggered the bananas to ripen.

The auxin in the oranges diffused into the bananas where the two fruits touched each other and triggered the bananas to ripen.

The oranges had released ethylene into the air, which triggered the bananas to ripen.

Text Solution

Verified by Experts
