A large persistent cotyledon in the embryo of the wheat grain is called

Options

A. Coleorhiza
B. Scutellum
C. Coleoptile
D. Epiblast

Answer

To solve the question regarding the large persistent cotyledon in the embryo of the wheat grain, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Wheat Grain**:
- Wheat is a monocot seed, which means it has one cotyledon. The cotyledon serves as a food storage organ for the developing embryo.

2. **Identify the Cotyledon**:
- In the case of wheat, the single cotyledon is not just any cotyledon; it is specifically adapted and has a particular name.

3. **Review the Options**:
- The options provided are:
- A) Coleorhiza
- B) Scutellum
- C) Coleoptile
- D) Epiblast

4. **Analyze Each Option**:
- **Coleorhiza**: This refers to the protective sheath covering the radical (embryonic root) of the seed. This is not the correct answer.
- **Scutellum**: This is the name given to the large, persistent cotyledon in the embryo of the wheat grain. This is the correct answer.
- **Coleoptile**: This is the sheath that covers the emerging shoot (plumule) of the seedling. This is not the correct answer.
- **Epiblast**: This term is not relevant in the context of wheat grain cotyledons. This is not the correct answer.

5. **Conclusion**:
- The correct answer is **B) Scutellum**, as it is the large persistent cotyledon found in the embryo of the wheat grain.

### Final Answer:
**The large persistent cotyledon in the embryo of the wheat grain is called Scutellum.**
