AP BIOLOGY

Detailed explanation-1: -Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Detailed explanation-2: -During photosynthesis, plants make carbohydrates from Carbon dioxide and water.

Detailed explanation-3: -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-4: -Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-5: -During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
