The filiform apparatus is present in

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the presence of the filiform apparatus in specific structures related to flowering plants.

2. **Identifying the Options:**
The options provided are:
- A) Synergids
- B) Generative cell
- C) Nuclear embryo
- D) Allurone layer

3. **Defining the Filiform Apparatus:**
The filiform apparatus is a specialized structure found in the female gametophyte of flowering plants. It is located in the synergids, which are part of the embryo sac.

4. **Location of the Filiform Apparatus:**
The filiform apparatus is specifically present in the synergids. Synergids are two cells located next to the egg cell within the embryo sac, and they play a crucial role in guiding the pollen tube during fertilization.

5. **Function of the Filiform Apparatus:**
The filiform apparatus helps in stimulating the generative cell of the pollen tube to release two male gametes during the process of fertilization.

6. **Conclusion:**
Based on the above information, the correct answer to the question is that the filiform apparatus is present in **synergids**.

**Final Answer:**
The filiform apparatus is present in **synergids**.
