Ethylene and Fruit Ripening: A Catalyst for Freshness

How does ethylene play a role in the ripening process of fruits?

A. By changing the color of fruits
B. By slowing down the ripening process
C. By preventing fruits from rotting
D. By accelerating the ripening process

Answer:

The correct answer is D. By accelerating the ripening process.

Ethylene is a naturally occurring plant hormone that plays a crucial role in accelerating the ripening process of fruits. When fruits are exposed to ethylene, such as by placing a ripe apple or banana near unripe fruits, the gas speeds up the ripening process by triggering various biochemical changes within the fruit.

One interesting experiment conducted by Lind demonstrated the significance of ethylene in fruit ripening. Additionally, farmers utilize ethylene by spraying it on green peppers to hasten the ripening process and promote color change.

By understanding how ethylene functions as a catalyst for fruit ripening, we can better appreciate the natural processes that contribute to the freshness and flavor of our fruits.
