Understand the process of photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. This process involves the transformation of carbon dioxide and water into glucose and oxygen, using light energy.
Identify the reactants and products: In photosynthesis, the reactants are carbon dioxide (CO2), water (H2O), and light energy. The products are glucose (C6H12O6) and oxygen (O2).
Write the balanced chemical equation: The balanced equation for photosynthesis is 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This equation shows that six molecules of carbon dioxide and six molecules of water, in the presence of light energy, produce one molecule of glucose and six molecules of oxygen.
Analyze the given options: Compare each option with the balanced equation for photosynthesis. The correct representation should match the balanced equation in terms of reactants, products, and their stoichiometric coefficients.
Select the correct option: The option that correctly represents the balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This matches the standard equation for photosynthesis, confirming the transformation of reactants into products.
