Final answer:
The reactants for photosynthesis are carbon dioxide, water, and sunlight. Carbohydrates are a product, not a reactant, and oxygen is a byproduct of the process.
Step-by-step explanation:
The correct reactants for photosynthesis are carbon dioxide (CO₂), water (H₂O), and photons (sunlight). Therefore, from the provided options, the reactants for photosynthesis are b. CO₂, c. H₂O, and e. photons (sunlight). Oxygen (O₂) is not a reactant in this process; instead, it is a byproduct. Carbohydrates are a product of photosynthesis, not a reactant.
In photosynthesis, plants use chlorophyll to capture photons from sunlight, and they convert carbon dioxide and water into glucose and oxygen. The general chemical equation representing photosynthesis is:
6 CO₂ + 6 H₂O + photons → C₆H₁₂O₆ + 6 O₂
