Function of guiding and attracting pollen tube towards egg is done by

Options

A. egg cell
B. filiform apparatus
C. anitpodal cell
D. polar nuclei

Answer

**Step-by-Step Solution:**

1. **Identify the Structure Involved**: The question asks about the function of guiding and attracting the pollen tube towards the egg. The key structures involved in this process are the synergid cells located at the micropyle end of the ovule.

2. **Understand the Role of Synergids**: The synergids are specialized cells that play a crucial role in the fertilization process. They are located near the egg cell and are responsible for guiding the pollen tube towards the egg.

3. **Recognize the Filiform Apparatus**: Within the synergid cells, there are finger-like projections known as the filiform apparatus. This structure is essential for the interaction between the pollen tube and the ovule.

4. **Mechanism of Attraction**: The filiform apparatus helps in attracting the pollen tube by releasing chemical signals that guide the pollen tube to the egg cell. This ensures that the pollen tube enters the ovule at the correct location.

5. **Conclusion**: Therefore, the function of guiding and attracting the pollen tube towards the egg is primarily performed by the synergid cells, specifically through the action of the filiform apparatus.

**Final Answer**: The guiding and attracting of the pollen tube towards the egg is done by the synergid cells, specifically through the filiform apparatus.
