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 into 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?
The leaves and flowers of the roadside plants were comparatively very dull because the air quality near the roadside is very bad due to the emission of harmful gases and dust particles from automobiles. These dust particles get stuck with the plants and make them appear dull.
