Filifom apparatus is characteristic feature of :

Options

A. generative cell
B. nucellar embryo
C. aleurone cell
D. synergids

Answer

**Step-by-Step Solution:**

1. **Understanding the Filiform Apparatus**: The filiform apparatus is a specialized structure found in flowering plants. It is located at the micropylar end of the ovule.

2. **Identifying the Structure**: The filiform apparatus is formed from the cell wall of synergids, which are specialized cells located near the egg cell in the ovule.

3. **Characteristics of the Filiform Apparatus**: It consists of numerous finger-like projections that extend into the cytoplasm of the synergids. These projections help in the interaction with the pollen tube.

4. **Function of the Filiform Apparatus**: The primary function of the filiform apparatus is to guide the pollen tube towards the egg cell for fertilization. It plays a crucial role in the reception of the pollen tube.

5. **Conclusion**: Based on the characteristics and functions of the filiform apparatus, we conclude that it is a characteristic feature of synergids.

6. **Final Answer**: Therefore, the correct option is D, which is synergids.
