Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

Detailed explanation-3: -Carbohydrates are formed by green plants from carbon dioxide and water during the process of photosynthesis. Carbohydrates serve as energy sources and as essential structural components in organisms; in addition, part of the structure of nucleic acids, which contain genetic information, consists of carbohydrate.

Detailed explanation-4: -Aside from using complex carbohydrates to create the plant’s structure, plants store carbohydrates or use them for energy to grow. To use stored carbohydrates, plants take the glucose formed during photosynthesis and combine the carbohydrate with oxygen–a process called respiration–to release energy.

Detailed explanation-5: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
