The part of the embryo between the cotyledons and the embryonic root (radicle) is called :

Options

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

Explanation

To solve the question, "The part of the embryo between the cotyledons and the embryonic root (radicle) is called:", we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Components of the Embryo**:
- The embryo consists of several parts: cotyledons, radicle (embryonic root), and other structures like the hypocotyl and epicotyl.

2. **Understand the Function of Cotyledons**:
- Cotyledons are the first leaves of the plant and serve as a source of nutrition for the germinating seed.

3. **Locate the Radicle**:
- The radicle is the part of the embryo that develops into the root of the plant.

4. **Determine the Structure Between Cotyledons and Radicle**:
- The structure that connects the cotyledons to the radicle is crucial for understanding the anatomy of the embryo.

5. **Identify the Correct Term**:
- The part of the embryo that lies between the cotyledons and the radicle is known as the hypocotyl.

6. **Conclusion**:
- Therefore, the answer to the question is "hypocotyl".

### Final Answer:
The part of the embryo between the cotyledons and the embryonic root (radicle) is called the **hypocotyl**.
