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 Embryo Sac**: The embryo sac is a structure within the ovule of flowering plants that contains the female gametes. It typically consists of seven cells, including the egg cell and synergids.

2. **Identifying the Synergids**: Among the cells in the embryo sac, the synergids are located at the micropylar end. There are usually two synergids present.

3. **Defining the Filiform Apparatus**: The filiform apparatus is a specialized structure found in the synergids. It consists of cellular thickenings that help in guiding the pollen tube towards the egg cell during fertilization.

4. **Locating the Filiform Apparatus**: The filiform apparatus is specifically found at the micropylar end of the synergids. This positioning is crucial as it facilitates the reception of the pollen tube.

5. **Conclusion**: Based on the above understanding, the filiform apparatus is present at the micropylar part of the synergid.

### Final Answer:
The filiform apparatus is present at the **micropylar part of the synergid**.
