Biciliate antherozoids are found in ferns.

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- Antherozoids are the male gametes in plants.
- Biciliate refers to having two cilia or flagella.

2. **Identifying the Structure in Ferns**:
- In ferns, the male gametes (antherozoids) are indeed present, but they are characterized by having multiple flagella, not just two.

3. **Comparing with Other Plants**:
- In contrast, mosses have biciliate antherozoids, which means they possess exactly two flagella.

4. **Conclusion**:
- The statement "Biciliate antherozoids are found in ferns" is incorrect. Ferns have multi-flagellated antherozoids, which means they have more than two flagella.

5. **Final Answer**:
- The statement is false.
