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: -When chlorophyll absorbs energy from sunlight, an electron in the chlorophyll molecule is excited from a lower to a higher energy state. The excited electron is more easily transferred to another molecule. A chain of electron-transfer steps follows, ending when an electron is transferred to a carbon dioxide molecule.
Detailed explanation-3: -The function of chlorophyll is to capture the light energy of the sun and convert water and carbon dioxide to produce glucose and oxygen. Plants use glucose for the growth of different plant parts.
