A. Radical
B. Coleorhiza
C. Coleoptile
D. Plumule

Answer

**Step-by-Step Solution:**

1. **Understanding Plumule**: Plumule is the part of a seed that develops into the shoot of a plant. It is crucial for the growth of the plant as it will eventually develop into the stem and leaves.

2. **Identifying the Seed Structure**: In a seed, there are various structures that protect and support the developing plant. The outermost layer is known as the seed coat, which protects the seed from physical damage and desiccation.

3. **Locating the Plumule**: Inside the seed, the plumule is situated above the cotyledons (the seed leaves) and is part of the embryo.

4. **Understanding the Protective Structures**: The plumule is not directly exposed; it is protected by a specialized structure known as the collenchyma. The collenchyma provides support and protection to the plumule as it begins to grow.

5. **Conclusion**: Therefore, the plumule is enclosed by the collenchyma, which is the correct answer.

**Final Answer**: The plumule is enclosed by the collenchyma.
