Which pigment acts directly to convert light energy to chemical energy ?

Options

A. Chlorophyll a
B. Chlorophyll b
C. Xanthophyll
D. Carotenoid

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which pigment is responsible for converting light energy into chemical energy during photosynthesis.

2. **Identifying the Options**: The options provided are:
- A) Chlorophyll A
- B) Chlorophyll B
- C) Xanthophyll
- D) Carotene

3. **Analyzing Each Option**:
- **Chlorophyll A**: This is the primary pigment involved in photosynthesis. It directly absorbs light energy and converts it into chemical energy.
- **Chlorophyll B**: This pigment assists in capturing light energy but does not directly convert it into chemical energy.
- **Xanthophyll**: This is a carotenoid pigment that helps in light absorption but is not directly involved in the conversion process.
- **Carotene**: Similar to xanthophyll, it assists in light absorption but does not convert light energy into chemical energy.

4. **Conclusion**: Based on the analysis, the pigment that acts directly to convert light energy to chemical energy is **Chlorophyll A**.

5. **Final Answer**: The correct answer is **Option A: Chlorophyll A**.
