Let's identify the reactants of the photosynthesis process by analyzing the photosynthesis equation.
The chemical equation for photosynthesis is:
[tex]\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{Energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \][/tex]
In this process:
- Reactants are the substances that start the chemical reaction.
- Products are the substances that are produced by the chemical reaction.
From the photosynthesis equation, we can see that the reactants are:
- Carbon dioxide (6 [tex]\(\text{CO}_2\)[/tex])
- Water (6 [tex]\(\text{H}_2\text{O}\)[/tex])
- Energy (typically from sunlight)
And the products are:
- Glucose ([tex]\(\text{C}_6\text{H}_{12}\text{O}_6\)[/tex])
- Oxygen (6 [tex]\(\text{O}_2\)[/tex])
Now, let's evaluate the provided options to determine which one correctly lists the reactants of photosynthesis:
1. Option 1: [tex]\(6 \text{CO}_2 + 6 \text{H}_2 \text{O} + \text{Energy}\)[/tex]
- This option matches the reactants part of the photosynthesis equation correctly.
2. Option 2: [tex]\(\text{C}_6 \text{H}_{12} \text{O}_6 + 6 \text{O}_2\)[/tex]
- This option lists the products of photosynthesis, not the reactants.
3. Option 3: [tex]\(\text{CO}_2 + \text{H}_2\text{O} + \text{Energy}\)[/tex]
- This option is close but incomplete. It lists the correct substances but missing the correct stoichiometry from the balanced equation (it should be 6 [tex]\(\text{CO}_2\)[/tex] and 6 [tex]\(\text{H}_2\text{O}\)[/tex]).
4. Option 4: [tex]\(\text{C}_6 \text{H}_{12} \text{O}_6 + \text{O}_2\)[/tex]
- This is also incorrect as it similarly lists parts of the products of photosynthesis.
Based on this analysis, the correct option that lists the reactants of photosynthesis is:
Option 1: [tex]\(6 \text{CO}_2 + 6 \text{H}_2 \text{O} + \text{Energy}\)[/tex]
Therefore, the correct answer is:
[tex]\[ 1 \][/tex]
