Stimulus of flow temperature in vernalisation is perceived by

Options

A. Leaves
B. Embryo of the seed
C. Flower
D. Pericarp

Answer

**Step-by-Step Solution:**

1. **Understanding Vernalization**:
- Vernalization is the process by which plants require a period of cold temperatures to trigger flowering. This is crucial for plants that need to ensure they flower at the right time of year, typically in spring.

2. **Identifying the Stimulus**:
- The stimulus in vernalization is low temperature. This low temperature is essential for the plant to transition from a vegetative state to a flowering state.

3. **Determining the Perception Site**:
- The question asks where the stimulus of low temperature is perceived. We need to identify which part of the plant is responsible for detecting this cold stimulus.

4. **Evaluating the Options**:
- The options provided are:
1. Leaves
2. Embryo of the seeds
3. Flower
4. Pericarp
- Among these options, the leaves are known to play a significant role in perceiving environmental cues, including temperature changes.

5. **Conclusion**:
- The correct answer is that the stimulus of low temperature in vernalization is perceived by the **leaves** of the plant.

**Final Answer**: The stimulus of low temperature in vernalization is perceived by **leaves**.
