Function of filiform apparatus is to :-

Options

A. Guide the entry of pollen tube
B. Recognize the suitable pollen at sigma
C. Stimulate division of generative cell
D. Produce nectar

Answer

### Step-by-Step Solution:

1. **Understanding the Filiform Apparatus**:
- The filiform apparatus is a structure found in the egg apparatus of flowering plants. It consists of specialized cells called synergids, which are located next to the egg cell.

2. **Structure of the Filiform Apparatus**:
- Within the synergid cells, there are finger-like projections known as the filiform apparatus. These projections extend towards the pollen tube.

3. **Role of the Filiform Apparatus**:
- The primary function of the filiform apparatus is to guide the pollen tube towards the egg cell. When pollen lands on the stigma, it germinates and forms a pollen tube that grows toward the ovule.

4. **Guiding the Pollen Tube**:
- The filiform apparatus acts as a guiding structure, helping the pollen tube navigate to the egg cell for fertilization. It provides a pathway for the pollen tube to enter the ovule.

5. **Conclusion**:
- Therefore, the function of the filiform apparatus is to guide the entry of the pollen tube into the egg cell, facilitating successful fertilization.

### Final Answer:
The function of the filiform apparatus is to guide the entry of the pollen tube into the egg cell.
