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 organelles that contain a green pigment and are selectively found in plants are called chloroplasts. These organelles contain chlorophyll pigment, which allows them to capture solar energy to prepare food.
Detailed explanation-4: -Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy.
Detailed explanation-5: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
