Embryo sac is present embedded in nucellus at which end of ovule?

Options

A. Micropylar end
B. Chalazal end
C. In the center
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Ovule**: The ovule is a crucial part of the flower's reproductive system, located within the ovary. It contains the embryo sac, which is essential for fertilization and seed development.

2. **Identifying the Ends of the Ovule**: The ovule has two distinct ends:
- **Micropilar End**: This is the end where the embryo sac is located and where the pollen tube enters during fertilization.
- **Chalazal End**: This is the opposite end of the ovule.

3. **Locating the Embryo Sac**: The embryo sac, which contains the egg cell and synergids, is embedded in the nucellus. It is specifically located at the micropilar end of the ovule.

4. **Conclusion**: Based on the structure of the ovule and the position of the embryo sac, we can conclude that the embryo sac is present embedded in the nucellus at the micropilar end of the ovule.

**Final Answer**: The embryo sac is present embedded in the nucellus at the micropilar end of the ovule.
