Question

How does air pollution affect plants’ health and
growth?

Answer 1

Dear Student,

Air pollution can have adverse effect on the growth and development of the plants.
The two effects of air pollution on plants are:
1. Photochemical smog, an air pollutant, forms a layer on the leaves and blocks carbon dioxide from being absorbed by the leaves. This leads to a reduction of the photosynthetic activity in plants, thereby curbing its growth.
2. Acid rains which contain sulphuric acid and nitric acid can harm plants' growth and can also cause premature leaf falls.
