- **Multiflagellate**: This means they have multiple flagella.
- **Coiled**: The shape of the sperm cells is often coiled or streamlined.

4. **Analyzing the Options**: Given the options:
- Biciliate and coiled
- Multiflagellate and sickle-shaped
- Multiflagellate and coiled
- Biciliate and streamlined

We need to identify which option correctly describes the sperm of ferns.
