The part of the embryonal axis that remains above the level of attachment of scutellum is

Options

A. plumule
B. coleoptile.
C. hypocotyl.
D. epicotyl

Answer

To determine which part of the embryonal axis remains above the level of attachment of the scutellum, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Structure**: The embryonal axis of a seed consists of several parts, including the plumule, hypocotyl, and epicotyl. The scutellum is a part of the seed that serves as a food storage tissue.

2. **Analyzing the Options**:
- **Option 1: Plumule**: The plumule is the part of the embryo that develops into the shoot. However, it is located above the scutellum, making this option potentially correct.

- **Option 2: Coleoptile**: The coleoptile is a sheath that protects the young shoot as it emerges from the soil. It does not refer to a part of the embryonal axis that is above the scutellum, so this option is incorrect.

- **Option 3: Hypocotyl**: The hypocotyl is the part of the stem of a germinating seedling that is below the cotyledons (scutellum). Therefore, this option is also incorrect as it is located below the scutellum.

- **Option 4: Epicotyl**: The epicotyl is the portion of the embryonal axis that is above the cotyledons (scutellum). This is the part that grows into the stem and leaves of the plant.

3. **Conclusion**: The correct answer is **Epicotyl**, as it is the part of the embryonal axis that remains above the level of attachment of the scutellum.

### Final Answer:
The part of the embryonal axis that remains above the level of attachment of the scutellum is **Epicotyl**.
