Stem develops from :-

Options

A. Radicle
B. Plumule
C. Hypocotyl
D. Coleoptile

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Embryo Structure**: In a seed, the embryo consists of different parts, including the radical, plumule, and cotyledons. Each part has a specific role in the development of the plant.

2. **Identifying the Parts**:
- **Radical**: This part of the embryo develops into the root system of the plant.
- **Plumule**: This part develops into the shoot system, which includes the stem and leaves.
- **Hypocotyl**: This is the part of the stem below the cotyledons and above the root.
- **Cotyledons**: These are the seed leaves that provide nutrients to the developing plant.

3. **Determining the Function of Each Part**:
- The radical is responsible for root development.
- The plumule is responsible for stem and leaf development.
- The hypocotyl connects the root and the shoot but does not develop into the stem itself.

4. **Conclusion**: Since the question asks which part develops into the stem, we focus on the plumule. The plumule is the part of the embryo that grows into the shoot system, which includes the stem.

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