The Ripening Signal: Ethylene Hormone Explained

One overripe banana in a bowl of fruit accelerates the ripening of everything around it, and the molecule responsible for that effect is a gas. Ethylene hormone explained reveals a plant hormone unlike any other, operating in...

Questions: 20 | Attempts: 12 | Last updated: Mar 8, 2026

Sample Question 1
Unlike most other plant hormones, what is the physical state of ethylene at room temperature?

A gas

A liquid

A solid

A plasma

A crystal

Sample Question 2
As the ethylene hormone explained in many textbooks shows, what is its most famous effect on a piece of fruit?

It triggers the ripening process

It makes the fruit grow larger

It prevents the fruit from being eaten

It turns the fruit back into a flower

It causes the fruit to freeze

Sample Question 3
With ethylene hormone explained as a signal for seasonal changes, it is the primary driver of leaf abscission (falling leaves) in autumn.

True

False
