Where the antheridia and archegonia are located in fern ?

Answer

**Step-by-Step Solution:**

1. **Understanding the Structures**: In ferns, the reproductive structures are called antheridia and archegonia. Antheridia are the male gametangia that produce sperm, while archegonia are the female gametangia that produce eggs.

2. **Identifying the Gametophyte Stage**: The gametophyte stage in ferns is known as the prothallus. This is a small, heart-shaped structure that is typically green and photosynthetic.

3. **Location of Antheridia and Archegonia**: Both antheridia and archegonia are located on the prothallus. The antheridia are usually found on the lower surface of the prothallus, while the archegonia are located near the notch of the prothallus.

4. **Function of Antheridia and Archegonia**: The antheridia release sperm, which swim through water to reach the archegonia, where fertilization occurs. This fusion of gametes leads to the formation of a zygote, which will develop into the sporophyte generation.

5. **Conclusion**: Therefore, the correct answer to the question is that the antheridia and archegonia are located on the prothallus in ferns.
