Why do grapes rotten before bananas and apples?

Answer 1

An apple rots faster than an orange because in plant science many hormones are used in order to drop fruit, ripen fruit, elongate the stem, etc. One is called ethylene this causes fruit to rot. It is transported as a gas through the air. Therefore if a rotten banana is placed in a bushel of apples, the apples will go bad. Therefore the gas enters the fruit and causes it to decay. (The purpose for the plant is because the fruits contain the future plants seeds.)

Now why do apples rot faster than Oranges, this is because of the peels, and climate. An apple has a smaller peel, and therefore ethylene can enter easily. Oranges have a very thick peel, and the gas takes a while to enter the fruit.

The reason for the peels lies in climate of where oranges and apples are farmed. Oranges need that thick peel because the weather where oranges are grown is tropic and hot. Therefore rotting occurs too fast. However the orange regulates it with its thick peel. Apples are grown further north where the climate is not as severe, therefore it does not need that thick peel.
