In angiosperms during development of embryo, the suspensor cell develops from

Options

A. Oospore
B. Integument
C. Endosperm
D. Cotyledon.

Answer

To solve the question regarding the development of the suspensor cell in angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to understand what the oospore is. The oospore is the fertilized egg cell in angiosperms that develops into the embryo.

2. **Division of Oospore**:
- The oospore undergoes a process of division. It transversely divides into two cells: a terminal cell and a basal cell.

3. **Identifying the Suspensor Cell**:
- Among the two cells formed from the oospore, the basal cell is the one that develops into the suspensor cell. The suspensor is crucial as it anchors the developing embryo and facilitates nutrient transfer.

4. **Location of the Suspensor Cell**:
- The suspensor cell is located at the micropylar end of the embryo sac. The terminal cell, on the other hand, will develop into the embryo itself.

5. **Conclusion**:
- Therefore, the suspensor cell develops from the oospore. The correct answer to the question is option number one: oospore.

### Final Answer:
The suspensor cell in angiosperms during the development of the embryo develops from the oospore.
