The correct difference between the embryonic development of monocot and dicot plants is

Options

A. In monocots, suspensor is single celled while in dicots it contains 6 - 10 cells
B. In monocots endosperm is formed before embryo while in dicots embryo is formed before endosperm
C. In dicots , coleoptile and coleorhiza are seen while they are not seen in monocots
D. In dicots the growth of embryo is lateral but in monocots it is vertical

Answer

To determine the correct difference between the embryonic development of monocot and dicot plants, we will analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Suspensor**:
- In monocots, the suspensor is typically single-celled.
- In dicots, the suspensor consists of multiple cells, usually around 6 to 10 cells.
- **Conclusion**: This statement is correct.

2. **Formation of Endosperm and Embryo**:
- In monocots, the endosperm is formed before the embryo.
- In dicots, the embryo is formed before the endosperm.
- However, it is known that the endosperm must be formed first to provide nutrition to the developing embryo.
- **Conclusion**: This statement is incorrect.

3. **Presence of Coleoptile and Coleorhiza**:
- Coleoptile is a protective sheath covering the plumule (shoot axis) and is found in monocots.
- Coleorhiza is a protective sheath covering the radical (root axis) and is also found in monocots.
- The statement claims that these structures are found in dicots, which is incorrect.
- **Conclusion**: This statement is incorrect.

4. **Growth Direction of Embryo**:
- In dicots, the growth of the embryo is vertical.
- In monocots, the growth of the embryo is lateral.
- The statement claims the opposite, which is incorrect.
- **Conclusion**: This statement is incorrect.

### Final Conclusion:
The only correct statement regarding the embryonic development of monocots and dicots is that in monocots, the suspensor is single-celled, while in dicots, it contains multiple cells (6 to 10). Therefore, the answer to the question is **Option 1**.
