Question

Some effects of $S{O}_2$ and its transformation products on plants includes

• A. Chlorophyll destruction
• B. Plasmolysis
• C. Golgi body destruction
• D. Exosmosis

Answer 1

The correct option is A Chlorophyll destruction

Plants absorb and metabolize sulfur dioxide through stomata on leaves. A high atmospheric concentration of sulfur dioxide results in extensive tissue damage because the sulfur dioxide reacts with the plant water to form sulfuric acid that damages plant cells by the breakdown of chlorophyll molecule due loss of Mg++ leading to decreased photosynthesis. Thus the correct answer is option A.
