Question

All of the following are harmful effects of high energy UV radiations, except

• A. Weaken the immune system
• B. Harm eyesight causing cataract
• C. Increased yield of crop plants
• D. Increased embryonic mortality

Answer 1

The correct option is C Increased yield of crop plants

High energy UV radiations are not good for plants. They can destroy the chlorophyll present in the leaves, which impairs the process of photosynthesis, and thereby decreasing the crop yield. Optimum amount of UV radiation is useful for the plants.
