Which combination lists three requirements needed for photosynthesis in plants?

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

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the process of photosynthesis, which is how plants convert light energy into chemical energy stored in glucose.
2. Step 2: Identify the raw materials required for photosynthesis. These include light energy (usually from the sun), carbon dioxide (CO\_2) from the air, and water (H\_2O) absorbed by the roots.
3. Step 3: Recognize that nitrogen gas, oxygen, glucose, and carbon monoxide are not direct inputs for photosynthesis. Nitrogen gas is important for plant nutrition but not for photosynthesis itself.
4. Step 4: Recall the general photosynthesis equation: \$6CO\_2 + 6H\_2O + light \ energy \rightarrow C\_6H\_{12}O\_6 + 6O\_2$, which shows carbon dioxide and water as reactants and glucose and oxygen as products.
5. Step 5: Conclude that the correct combination of requirements for photosynthesis is light energy, carbon dioxide, and water.
