What are the raw material for photosynthesis?

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (food). This process primarily occurs in the leaves of plants.

2. **Identifying Raw Materials**:
- The raw materials needed for photosynthesis include:
- **Sunlight**: This is the energy source that drives the photosynthesis process.
- **Chlorophyll**: This is the green pigment found in the chloroplasts of plant cells. It absorbs sunlight and is essential for capturing light energy.
- **Water (H2O)**: Plants absorb water from the soil through their roots, which is necessary for the photosynthesis process.
- **Carbon Dioxide (CO2)**: This gas is taken in from the atmosphere through small openings in the leaves called stomata.

3. **Summarizing the Raw Materials**:
- Therefore, the four essential raw materials for photosynthesis are:
- Sunlight
- Chlorophyll
- Water (H2O)
- Carbon Dioxide (CO2)

### Final Answer:
The raw materials for photosynthesis are sunlight, chlorophyll, water (H2O), and carbon dioxide (CO2).
