Explanation:
Detailed explanation-1: -Photosynthesis is the process by which green plants synthesise their own food from carbon dioxide and water in the presence of sunlight and chlorophyll. During this process, oxygen is released as a by-product.
Detailed explanation-2: -Sugars, made from water and carbon dioxide, are used to collect chemical energy. Water molecules split during photosynthesis to generate oxygen and hydrogen ions. As a result, plants expel oxygen, which is then used to reduce carbon dioxide and produce carbohydrates.
Detailed explanation-3: -When green plants perform photosynthesis, they take in carbon dioxide and release oxygen into the air.
