Detailed explanation-1: -The reactants of photosynthesis are carbon dioxide and water. We’ve established that plants need carbon dioxide (CO2) and water (H2O) to produce their food, but where do these reactants come from and how do they get where they need to go inside the plant?

Detailed explanation-2: -Photosynthesis produces water as a byproduct. During photosynthesis, plants take carbon dioxide ( C O 2 ), and water ( H 2 O ) from the air and soil. In the plant cell, carbon dioxide is reduced, which results in the gain of electrons, whereas water is oxidized, which results in the loss of electrons.

Detailed explanation-3: -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-4: -Individual water molecules can participate in the reaction as reactants or as catalysts. Water can contribute to the changes in the free energy of activation through solute-solvent interactions and solvent reorganization.

Detailed explanation-5: -The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water. The reactant water molecule is taken up from the soil by the roots for splitting and producing oxygen. Water is also a product of photosynthesis.
