Which set correctly lists three requirements needed for photosynthesis in most plants?

• A. Light energy, carbon dioxide, and water
• B. Nitrogen gas, water, and oxygen
• C. Oxygen, glucose, and light energy
• D. Carbon dioxide, glucose, and ATP

Answer: (A)

Verified step by step guidance

1. Understand that photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose.
2. Recall the main inputs required for photosynthesis: light energy, carbon dioxide (CO\_2), and water (H\_2O).
3. Recognize that light energy is captured by chlorophyll in the chloroplasts to drive the chemical reactions.
4. Know that carbon dioxide is taken from the air through the stomata, and water is absorbed by the roots from the soil.
5. Identify that the other options include substances not directly required as inputs for photosynthesis, such as nitrogen gas, oxygen, glucose, or ATP, which are either products or unrelated.
