Understand the process of photosynthesis: Photosynthesis is a chemical process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy stored in glucose.
Identify the general chemical equation for photosynthesis: The overall balanced chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
Determine the reactants in the photosynthesis equation: In the equation, the reactants are the substances that are consumed during the reaction. These are carbon dioxide (CO2) and water (H2O).
Consider the role of sunlight: While sunlight is not a reactant in the traditional sense, it provides the energy necessary for the reaction to occur, facilitating the conversion of carbon dioxide and water into glucose and oxygen.
Conclude with the identification of reactants: Based on the chemical equation and the process of photosynthesis, the reactants are carbon dioxide and water.
