On a Sunday morning Paheli’s friend visited her home. She wanted to see some flowering plants in the nearby garden. Both of them went to the garden. While returning from the garden they also observed some flowering plants on the road side. But to their surprise they found that the leaves and flowers of these roadside plants were comparatively very dull. Can you help them to know why?

उत्तर
The air quality present in the atmosphere which includes dust and soot particles released from vehicles, factories and chimneys makes the appearance of leaves and flowers dull which are planted on the roadside areas. The dust particles present in the air get deposited on the leaves and flowers and make them look dull.
