Cotyledonary node of embryo lies between

Options

A. Hypocotyl and radicle
B. Epicotyl and plumule
C. Epicotyl and hypocotyl
D. Cotyledons and radicle

Answer

To answer the question, "Cotyledonary node of embryo lies between," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Embryo**:
- The embryo consists of two main parts: the cotyledons and the embryonal axis. The embryonal axis can be further divided into the epicotyle and hypocotyle.

2. **Identifying Cotyledons**:
- In a dicot embryo, there are typically two cotyledons. In a monocot embryo, there is usually one cotyledon, known as the scutellum.

3. **Defining the Epicotyle and Hypocotyle**:
- The epicotyle is the part of the embryonal axis above the cotyledons, which will develop into the shoot system and leaves.
- The hypocotyle is the part of the embryonal axis below the cotyledons, connecting to the radical (the embryonic root).

4. **Locating the Cotyledonary Node**:
- The cotyledonary node is the region where the epicotyle and hypocotyle arise from the cotyledons. Therefore, it lies between the epicotyle (above) and the hypocotyle (below).

5. **Conclusion**:
- The cotyledonary node lies specifically between the epicotyle and the hypocotyle. Thus, the correct answer to the question is that the cotyledonary node of the embryo lies between the epicotyle and the hypocotyle.

### Final Answer:
The cotyledonary node of the embryo lies between the epicotyle and the hypocotyle.
