What is the role of suspensor during the development of embryo?

Answer

### Step-by-Step Text Solution:

1. **Definition of Suspensor**: The suspensor is a structure formed during the embryonic development of seed plants. It consists of a series of neck-like cells that extend from the embryo.

2. **Location**: The suspensor is located beneath the embryo, connecting it to the surrounding tissues, specifically the endosperm.

3. **Composition**: The suspensor is primarily made up of basal cells, typically consisting of 6 to 10 cells.

4. **Functions of the Suspensor**:
- **Physical Support**: The suspensor provides structural support to the developing embryo, ensuring it remains anchored as it grows.
- **Nutritional Supply**: It plays a crucial role in the transfer of nutrients from the surrounding endosperm to the embryo, facilitating its growth and development.
- **Embryo Positioning**: The suspensor helps in pushing the embryo towards the endosperm, allowing it to access the nutrients stored there effectively.

5. **Conclusion**: In summary, the suspensor is vital for the proper development of the embryo, providing support, nutrition, and positioning to ensure successful growth.
