Phytochrome responsible for flowering is

Options

A. Pigment present in floral buds
B. Hormone present in leaves
C. Pigment present is leaves
D. Enzymes present in floral buds.

Answer

**Step-by-Step Solution:**

1. **Understanding Phytochrome**: Phytochrome is a photoreceptor protein that plants use to detect light. It plays a crucial role in regulating various physiological processes, including flowering.

2. **Location of Phytochrome**: Phytochrome is primarily found in the leaves of flowering plants. This is where it perceives light and dark durations, which are essential for the flowering process.

3. **Function of Phytochrome**: Phytochrome is sensitive to red light and helps in the induction of flowering by responding to the light conditions. When plants receive the appropriate light signals, phytochrome activates the flowering process.

4. **Analyzing the Options**: The question provides several options regarding the nature of phytochrome:
- Pigment present in floral buds
- Hormone present in leaves
- Pigment present in leaves
- Enzymes present in floral buds

5. **Identifying the Correct Option**: Since phytochrome is a pigment and is predominantly located in the leaves, the correct answer is "pigment present in leaves." It is not a hormone or an enzyme, nor is it located in floral buds.

6. **Conclusion**: Therefore, the phytochrome responsible for flowering is indeed the pigment present in leaves.

**Final Answer**: Phytochrome responsible for flowering is the pigment present in leaves.
