Pollen tube deposits its inclusions in

Options

A. Central cell
B. Synergids
C. Oosphere
D. Antipodal cells.

Answer

### Step-by-Step Solution:

1. **Understanding the Pollen Tube Function**: The pollen tube is a structure that grows from the pollen grain after it lands on the stigma of a flower. Its primary function is to transport sperm cells to the ovule for fertilization.

2. **Identifying the Target Cells**: In the embryo sac of flowering plants, there are several types of cells, including:
- **Central Cell**: Contains two polar nuclei and will develop into the endosperm after fertilization.
- **Synergids**: Two cells located at the micropylar end of the embryo sac, which play a crucial role in guiding the pollen tube.
- **Antipodal Cells**: Typically three cells located at the opposite end of the embryo sac, which do not have a significant role in fertilization.
- **Phosphor**: This term seems to be a misnomer or irrelevant in this context.

3. **Role of Synergids**: The synergids are specifically designed to assist the pollen tube. They have a structure called the filiform apparatus that helps in attracting the pollen tube towards the ovule. This is done through the secretion of chemotactic substances.

4. **Conclusion**: Based on the function of the synergids and their role in guiding the pollen tube, the correct answer to the question is that the pollen tube deposits its inclusions in the **synergids**.

### Final Answer:
The pollen tube deposits its inclusions in **synergids**.
