Question

Which part of the plant is affected by $S{O}_2$ pollution?

• A. Chloroplast
• B. Mitochondria
• C. Endoplasmic Reticulum
• D. Lysosome

Answer 1

The correct option is A

Chloroplast

Sulfur dioxide $S{O}_2$ is a gas primarily emitted from fossil fuel combustion at power plants and other industrial facilities, as well as fuel combustion in mobile sources such as locomotives, ships, and other equipment. Excess $S{O}_2$ settles on the trees. It is then absorbed by leaves of the plants and is translocated to other parts. It decreases the photosynthesis rate of the chloroplast.
