Why do leaves become yellow in absence of light ?
Answered by admin @
When a plant fails to receive enough sunlight, the leaves turn from green to yellow.
Actually, the green colour of the leaves is caused due to the presence of chlorophyll that reacts in the presence of sunlight, resulting in photosynthesis.
As the leaves cannot produce foods due to the lack of sunlight, the plant becomes weaker and the leaves become yellow due to the degeneration of chlorophyll.
