Question

Choose the most suitable gas from the options given below that can be used for the ripening of fruits.

• A. $C{H}_4$
• B. $C{H}_2$
• C. $C_2{H}_4$
• D. $C{O}_2$

Answer 1

The correct option is C $C_2{H}_4$

Ethylene $\left(C_2{H}_4\right)$ is a gaseous plant growth hormone that promotes the ripening of fruits. But when the fruit is kept in an atmosphere full of ethylene, it can spoil the fruit's freshness as it stimulates the activity of the cellulase enzyme which breaks down the cellulose of the fruit wall. As a result, the tissues become soft.
