Detailed explanation-1: -Chlorophyll’s job in a plant is to absorb light-usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Detailed explanation-2: -Sunlight is absorbed by leaves of the plant. They use the absorbed sunlight during photosynthesis to make their own food.

Detailed explanation-3: -Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.

Detailed explanation-4: -Solar radiation is essential for plant growth. Plant leaves absorb sunlight and use it as the energy source for photosynthesis. The ability of a crop to collect sunlight is a function of leaf surface area or leaf area index.
