Pollen tube content is discharged in

Options

A. Central cell
B. Egg cell
C. Persistent synergid
D. Degenerated synergid

Answer

To answer the question "Where is the content of the pollen tube discharged?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollen Tube Development**:
- Pollen grains, when mature, develop a structure called the pollen tube. This tube is essential for the process of fertilization in flowering plants.

2. **Function of the Pollen Tube**:
- The primary function of the pollen tube is to transport the male gametes (sperm cells) from the pollen grain to the ovule for fertilization.

3. **Pathway of the Pollen Tube**:
- The pollen tube grows through the style of the flower and reaches the ovule, where fertilization occurs.

4. **Discharge of Pollen Tube Content**:
- The content of the pollen tube, which includes the sperm cells, is discharged at a specific location within the ovule.

5. **Identifying the Correct Location**:
- The pollen tube enters the ovule through the synergids, which are specialized cells that help facilitate the entry of the pollen tube.

6. **Understanding Synergids**:
- Synergids are located near the egg cell within the ovule. They play a crucial role in guiding the pollen tube.

7. **Degeneration of Synergids**:
- After the pollen tube discharges its contents, the synergids typically degenerate. This degeneration is a normal part of the fertilization process.

8. **Conclusion**:
- Therefore, the content of the pollen tube is discharged in the degenerated synergids.

### Final Answer:
The content of the pollen tube is discharged in the degenerated synergids.
