Answer: (A)

Verified step by step guidance

1. Understand the process of photosynthesis: Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy stored in glucose.
2. Identify the reactants and products: The general equation for photosynthesis is 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2. This indicates that carbon dioxide and water are used to produce glucose and oxygen.
3. Determine the main product: In the context of photosynthesis, the main product refers to the primary substance that is synthesized as a result of the process. Here, glucose (C6H12O6) is the main product as it is the primary energy storage molecule produced.
4. Consider the role of other substances: Oxygen is a by-product of photosynthesis, released into the atmosphere. Carbon dioxide and water are reactants, while sunlight is the energy source driving the reaction.
5. Conclude with the correct answer: Based on the understanding of the photosynthesis process, the main product is glucose, which is the primary energy storage molecule synthesized during the process.
