Question

How can the growing of plants help in control of air pollution?

Answer 1

Air pollution:

The air is meant to be polluted when there is the introduction of harmful and toxic substances in the air and it is termed as air pollution.

How can the growth of plants help in the control of air pollution:

1. Plants improve the air quality by absorbing the carbon dioxide from the atmosphere which they use in the process of photosynthesis (formation of food with the help of sunlight).
2. They absorb CO₂ and in turn release oxygen into the atmosphere.
3. They increase humidity by transpiring water vapour through stomata and they can also absorb pollutants on the external surfaces of the leaves.
4. Thus, growing plants will help in the control of air pollution.
