- In maize (corn), the plumule is protected by a sheath.

3. **Evaluate the Options**:
- **Scutellum**: This is a modified cotyledon in monocots like maize, but it does not cover the plumule.
- **Coleorhiza**: This is a protective sheath for the root (radicle) of the embryo, not the plumule.
- **Coleoptile**: This is the protective sheath that covers the plumule in monocot seeds, including maize.
- **Tegmen**: This is a layer of the ovule and does not relate to the plumule.

4. **Select the Correct Answer**:
