Function of synergids is to

Options

A. Attract pollen tube and bear its shock
B. Fuse with extra male gametes and form endosperm
C. Produce additional embryo
D. Protect egg from pathogens.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure**: The synergids are located at the micropilar end of the embryo sac, which is the female gametophyte in flowering plants. They are positioned adjacent to the egg cell.

2. **Identifying the Function**: The primary function of the synergids is to facilitate the entry of the pollen tube into the embryo sac.

3. **Mechanism of Action**: The synergids possess a structure known as the filiform apparatus. This structure plays a crucial role in guiding the pollen tube toward the egg cell.

4. **Attraction of Pollen Tube**: The synergids secrete certain substances that attract the pollen tube. This attraction is essential for ensuring that fertilization occurs.

5. **Shock Absorption**: Upon the arrival of the pollen tube, the synergids also act as a shock absorber. They help in protecting the egg cell during the process of fertilization.

6. **Conclusion**: Therefore, the function of synergids is to attract the pollen tube and bear its shock during fertilization.

**Final Answer**: The function of synergids is to attract the pollen tube and bear its shock.
