In embryosacs filiform apparatus is present at the

Options

A. micropylar part of the synergids
B. micropylar part of the egg
C. chalazal part of the synergids
D. chalazal part of the egg

Answer

To answer the question regarding the location of the filiform apparatus in the embryo sac, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Embryo Sac**:
- The embryo sac is a crucial part of the ovule in flowering plants. It contains several types of cells, including synergids, egg cells, and antipodal cells.

2. **Identifying the Components of the Embryo Sac**:
- The embryo sac consists of:
- **Micropylar End**: The end where the pollen tube enters.
- **Chalazal End**: The opposite end of the micropylar end.
- **Synergids**: Two cells located at the micropylar end, adjacent to the egg cell.
- **Egg Cell**: Located next to the synergids.
- **Antipodal Cells**: Three cells located at the chalazal end.

3. **Locating the Filiform Apparatus**:
- The filiform apparatus is a specialized structure found within the synergids. It consists of finger-like projections that help guide the pollen tube towards the egg cell for fertilization.

4. **Conclusion**:
- The filiform apparatus is specifically located at the **micropylar end of the synergids** in the embryo sac.

5. **Final Answer**:
- Therefore, the correct answer to the question is: **The filiform apparatus is present at the micropylar part of the synergids.**
