The portion of embryonal axis above the level of cotyledons is the .............and portion below the level of cotyledons is..............in dicotyledonous embryo :-

Options

A. Epicotyl, hypocotyl
B. Hypocotyl, epicotyl
C. Epicotyl, plumule
D. Hypocotyl, plumule

Answer

To answer the question regarding the portions of the embryonal axis in a dicotyledonous embryo, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding the Structure of a Dicotyledonous Embryo**:
- A dicotyledonous embryo typically consists of two main parts: the cotyledons, which are the seed leaves, and the embryonal axis, which connects the cotyledons to the root.

2. **Identifying the Portions of the Embryonal Axis**:
- The embryonal axis can be divided into two sections relative to the cotyledons:
- **Above the Cotyledons**: The portion of the embryonal axis that is located above the level of the cotyledons is known as the **epicotyl**.
- **Below the Cotyledons**: The portion of the embryonal axis that is located below the level of the cotyledons is referred to as the **hypocotyl**.

3. **Conclusion**:
- Therefore, the correct terms to fill in the blanks are:
- The portion of the embryonal axis above the level of cotyledons is the **epicotyl**.
- The portion below the level of cotyledons is the **hypocotyl**.

### Final Answer:
The portion of the embryonal axis above the level of cotyledons is the **epicotyl**, and the portion below the level of cotyledons is the **hypocotyl**.
