Detailed explanation-2: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.
Detailed explanation-3: -Q. Assertion: Energy is utilized from sunlight by plants during photosynthesis. It is the basis of life on our planet. Reason: Photosynthesis is the primary source of all food on earth and it is also responsible for the release of oxygen into the atmosphere.
