The stem develops from-

Options

A. Axillary bud.
B. Epicotyl
C. Radicle
D. Plumule

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Structure**: A seed consists of various parts, including the embryo, which is crucial for the development of the plant. The embryo has two main parts: the plumule and the radical.

2. **Identifying the Plumule and Radical**:
- The **plumule** is the part of the embryo that will develop into the shoot system, which includes the stem and leaves.
- The **radical** is the part that will develop into the root system.

3. **Determining the Origin of the Stem**: Since the stem is part of the shoot system, it is derived from the plumule. Therefore, when a seed germinates, the plumule will grow upwards to form the stem.

4. **Conclusion**: Based on this understanding, we can conclude that the stem develops from the plumule of the seed.

**Final Answer**: The stem develops from the plumule.
