What is the source of energy used during photosynthesis ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Begin by defining photosynthesis. It is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

2. **Identifying the Source of Energy**: The primary source of energy for photosynthesis is solar energy, which is derived from sunlight. This energy is captured by plants.

3. **Role of Chlorophyll**: Explain the role of chlorophyll, the green pigment found in the chloroplasts of plant cells. Chlorophyll absorbs sunlight and plays a crucial role in converting solar energy into chemical energy.
