Answer 1

MARK ME AS THE BRAINLIEST

Answer:

• many vehicles emit smoke and pollutants as they run.
• they are also known as the particulate matter.
• this particulate matter and dust along the road side get accumulated on the leaves of the trees.
• dust on the leaf surface affects plant growth and development.
• Leaves covered with dust receive less light for photosynthesis; this interferes with gas exchange between the leaf and air, and the reduction of leaf stomatal conductance influences plant biomass formation and yield.
• as the photosynthesis in the plants get weaker and weaker the chlorophyll in the leaves gets less and also the colour of the leaf will be faded.
