A typical dicotyledonous embryo consists of

Options

A. Radicle only
B. Radicle, embryonal axis and cotyledons
C. Cotylendons only
D. Embryo axis only.

Answer

To answer the question about what a typical dicotyledonous embryo consists of, we can break down the components step by step.

### Step-by-Step Solution:

1. **Understanding Dicotyledonous Embryos**:
- A dicotyledonous embryo is characterized by the presence of two cotyledons. The term "dicotyledon" itself indicates that there are two (di-) seed leaves (cotyledons).

2. **Components of the Embryo**:
- The typical components of a dicotyledonous embryo include:
- **Cotyledons**: These are the two seed leaves that store nutrients and provide energy for the initial growth of the plant.
- **Embryonal Axis**: This is the part of the embryo that connects the cotyledons to the root and shoot systems. It is divided into two parts:
- **Epicotyl**: The portion of the embryonal axis above the cotyledons, which will develop into the shoot.
- **Hypocotyl**: The portion of the embryonal axis below the cotyledons, which will develop into the root.

3. **Radicle**:
- The radicle is the part of the embryo that develops into the primary root. It is located at the lower end of the hypocotyl.

4. **Conclusion**:
- Therefore, a typical dicotyledonous embryo consists of:
- Two cotyledons
- An embryonal axis (which includes the epicotyl and hypocotyl)
- A radicle

### Final Answer:
A typical dicotyledonous embryo consists of the radical, embryonal axis, and cotyledons.
