Photosynthesis is defined as using sunlight to make food.

• A. Releasing energy from glucose
• B. Consuming oxygen for energy
• C. Using sunlight to make food
• D. Using water to break down glucose

Answer: (C)

Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose, using sunlight to drive reactions that combine carbon dioxide and water to form glucose and release oxygen as a byproduct. Saying photosynthesis uses sunlight to make food captures this idea: light energy is captured and used to synthesize a sugar that serves as the organism’s food. The other statements describe different processes: releasing energy from glucose happens in cellular respiration, not when plants build glucose; consuming oxygen for energy is also respiration; using water to break down glucose refers to breaking down glucose rather than making it.
