Question

Stove gas is responsible for _______

• A. \( \text{Ripening of apples} \)
• B. \( \text{Yellowing of lemons} \)
• C. \( \text{Development of shoots} \)
• D. \( \text{Stimulation of latex flow} \)

Hint:

Ethylene is a plant hormone that acts as a ripening agent. Exposure of fruits to sources of ethylene gas, like stove gas, can accelerate their ripening and color changes.

Answer 1

The Correct Option is B

Stove gas, which contains ethylene, is known to promote the ripening and senescence of fruits. In the context of the given options, the yellowing of lemons is associated with the degradation of chlorophyll, a process accelerated by ethylene. While ethylene also plays a role in the ripening of apples, the yellowing of lemons is a more direct and visually apparent effect related to stove gas exposure.
