Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.
Detailed explanation-2: -Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive.
Detailed explanation-3: -Glucose consists of three elements such as carbon, hydrogen and oxygen. 6 carbon atoms bonded together as a chain with additional atoms of oxygen and hydrogen.
Detailed explanation-4: -The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
