Answer

To answer the question "Stem originates from which part at the time of seed germination?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Seed Structure**: A seed consists of several parts, including the embryo, which is further divided into different regions: the plumule, radicle, and cotyledons.

2. **Identify the Plumule**: The plumule is the part of the embryo that will develop into the stem and leaves of the plant. It is located above the cotyledons.

3. **Identify the Radicle**: The radicle is the part of the embryo that develops into the primary root. It is located below the cotyledons.

4. **Clarify Other Terms**:
- **Cotyledon**: This is the part of the seed that provides nourishment to the developing plant. In monocots, it can be modified.
- **Coleorhiza**: This is a sheath that protects the radicle in germinating seeds, particularly in grasses.

5. **Conclusion**: At the time of seed germination, the stem originates from the plumule.

### Final Answer:
The stem originates from the **plumule** at the time of seed germination.
