Which pigment is responsible for flowering in plant?

Options

A. Phytochrome
B. Cytochrome
C. Anthocyanin
D. Xanthophyll

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the specific pigment responsible for flowering in plants. We need to identify which of the given options is correct.

2. **Reviewing the Options**: The options provided are:
- Phytochrome
- Cytochrome
- Anthocyanin
- Xanthophyll

3. **Identifying the Correct Pigment**:
- Phytochrome is known to play a significant role in regulating flowering, particularly in long-day plants. It is a photoreceptor that absorbs light and influences various developmental processes in plants.
- Cytochrome is primarily involved in electron transport and cellular respiration, not directly in flowering.
- Anthocyanin is a pigment responsible for red, purple, and blue colors in plants but does not play a direct role in flowering.
- Xanthophyll is a type of carotenoid and is involved in photosynthesis, not in the flowering process.

4. **Conclusion**: Based on the information, phytochrome is the pigment that stimulates flowering in long-day plants and inhibits flowering in short-day plants. Therefore, the correct answer is **Phytochrome**.
