Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. It primarily occurs in the chloroplasts of plant cells.

2. **Components Involved**:
- The main components required for photosynthesis are:
- Carbon dioxide (CO₂) from the atmosphere.
- Water (H₂O) absorbed from the soil.
- Sunlight, which provides the energy needed for the reaction.
- Chlorophyll, the green pigment in plants that captures light energy.

3. **Type of Process**:
- Photosynthesis is classified as an anabolic process because it builds complex molecules (glucose) from simpler ones (carbon dioxide and water).

4. **Photosynthesis Reactions**:
- Photosynthesis consists of two main stages:
- **Light Reactions**: These occur in the thylakoid membranes of the chloroplasts and require sunlight. Water is split (photolysis) to release oxygen.
- **Dark Reactions (Calvin Cycle)**: These occur in the stroma of the chloroplasts and do not require light directly. They utilize the ATP and NADPH produced in the light reactions to fix carbon dioxide into glucose.

5. **The Photosynthesis Equation**:
- The overall balanced equation for photosynthesis can be written as:
\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \]
- This equation indicates that six molecules of carbon dioxide and six molecules of water, in the presence of light energy, produce one molecule of glucose and six molecules of oxygen.

6. **Conclusion**:
- The correct equation for photosynthesis is:
\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \xrightarrow{\text{light energy}} \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \]
- Therefore, the correct answer to the question is option 2.
