In oxygenic photosynthesis in plants, which set correctly lists the main inputs (reactants) required to produce sugars?

• A. Glucose, water, and light energy
• B. Carbon dioxide, water, and light energy
• C. Oxygen and glucose
• D. Carbon dioxide and oxygen

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the process of oxygenic photosynthesis, which occurs in plants and involves converting light energy into chemical energy stored in sugars.
2. Step 2: Identify the main reactants (inputs) required for photosynthesis. These are the substances that the plant takes in to produce sugars.
3. Step 3: Recall the general photosynthesis equation: \$6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2$.
4. Step 4: From the equation, note that carbon dioxide (\(\text{CO}_2\)), water (\(\text{H}_2\text{O}\)), and light energy are the main inputs required to produce glucose (a sugar) and oxygen.
5. Step 5: Conclude that the correct set of inputs for oxygenic photosynthesis is carbon dioxide, water, and light energy.
