Which of the following in embryo sac of angiosperms shows filiform appratus

Options

A. Antipodals
B. Polar nuclei
C. Egg
D. Synergids.

Answer

To solve the question regarding which part of the embryo sac in angiosperms shows the filiform apparatus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Embryo Sac**: The embryo sac in angiosperms is a female gametophyte that contains several important structures, including antipodals, polar nuclei, egg cells, and synergids.

2. **Identify the Components**:
- **Antipodals**: These are located at the chalazal end of the embryo sac and typically do not have a filiform apparatus.
- **Polar Nuclei**: These are found in the central cell of the embryo sac and are not associated with a filiform apparatus.
- **Egg Cell**: This is located at the micropylar end but does not have a filiform apparatus.
- **Synergids**: These are located near the egg cell at the micropylar end and are known to have a filiform apparatus.

3. **Focus on Synergids**: The synergids are characterized by the presence of finger-like projections known as the filiform apparatus. These structures play a crucial role in guiding the pollen tube towards the egg cell for fertilization.

4. **Conclusion**: Based on the identification of the components and their functions, the correct answer to the question is that the filiform apparatus is found in the **synergids**.

### Final Answer:
The part of the embryo sac in angiosperms that shows the filiform apparatus is **synergids** (Option D).
