Phytochrome which is a photoreceptor for photoperiodic induction can be extracted from

Options

A. growing bud
B. cotyledons
C. leaves
D. stem

Answer

**Step-by-Step Text Solution:**

1. **Understanding Phytochrome**: Phytochrome is a type of photoreceptor found in plants, bacteria, and fungi. It plays a crucial role in detecting light, particularly in the red and far-red regions of the light spectrum.

2. **Role of Phytochrome**: Phytochromes are involved in regulating various aspects of plant development. This includes processes such as seed germination, chlorophyll synthesis, leaf movement, and the timing of flowering in adult plants.

3. **Photoperiodic Induction**: This term refers to the process by which plants produce a flowering stimulus in response to specific day lengths or photoperiods. The stimulus is generated in the leaves and then transported to the stem apex, where it triggers flowering.

4. **Source of Phytochrome**: Since phytochrome is involved in the photoperiodic induction process and is found in plants, the primary source from which phytochrome can be extracted is the leaves of the plant.

5. **Conclusion**: Therefore, the answer to the question is that phytochrome can be extracted from the leaves.

**Final Answer**: Phytochrome can be extracted from the leaves.
