The part of embryo axis between plumule and cotyledonary node is called

Options

A. epicotyl
B. hypocotyl
C. hilum
D. raphe

Answer

To determine the part of the embryo axis between the plumule and the cotyledonary node, we can analyze the options provided:

1. **Understanding the Terms**:
- **Plumule**: This is the part of the embryo that develops into the shoot, which will eventually grow into the stem and leaves.
- **Cotyledonary Node**: This is the point where the cotyledons (the seed leaves) are attached to the embryo axis.

2. **Analyzing the Options**:
- **Apicotyle**: This term refers to the section of the embryo axis that lies between the plumule and the cotyledonary node.
- **Hypocotyle**: This is the part of the embryo axis that is located between the radical (the embryonic root) and the cotyledonary node.
- **Hilum**: This is the scar on the seed where the funicle (the stalk attaching the seed to the ovule) was attached; it does not refer to a part of the embryo axis.
- **Raphe**: This is the structure formed by the fusion of the ovule with the funicle; it is not part of the embryo axis.

3. **Conclusion**:
- Since we are looking for the part of the embryo axis that is specifically between the plumule and the cotyledonary node, the correct answer is **Apicotyle**.

### Final Answer:
The part of the embryo axis between the plumule and the cotyledonary node is called the **Apicotyle**.
