Let’s compare the reproductive systems of a fern and a peach!
Ferns:
1. Ferns reproduce without ___________ or __________.
2. Ferns produce .
3. Spores reproduce by .
4. Spores release into the and become gametophytes. They are very tiny and only one cell thick.
5. The underside of the gametophyte has both and reproductive structures and they produce sperm or eggs.
6. The sperm has to swim through to reach the egg, which stays on the gametophyte. That’s why ferns are usually in .
