The two reactants to photosynthesis are what?

The two reactants in photosynthesis are carbon dioxide (CO₂) and water (H₂O). Plants use sunlight to convert these reactants into glucose (C₆H₁₂O₆) and oxygen (O₂) through a series of chemical reactions in the chloroplasts. This process is essential for producing energy in the form of glucose, which serves as food for the plant and, indirectly, for other organisms.
