Answer 2

When a banana ripens, we can observe the following changes-

• Its color is changed from green to yellow. This is because in unripened bananas, the chlorophyll pigments are present that starts breaking down when banana starts ripening.
• The banana becomes soft and sweet. This is because the starch present inside the banana is now converted into sugars due to the action of ethylene hormone.
