Question 20
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?
The road side plants had probably some dust and soot deposited
on them and thus appeared dull.
