I answered that with fern spore, but I'm not too sure. I also had that as my question, also. I hope it's correct. :D
Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.
Archegonia and antheridia do not mature at the same time on a prothallus to prevent self-fertilization and promote genetic diversity. By producing mature reproductive structures at different times, the prothallus increases the chances of cross-fertilization with gametes from other individuals.
Prothallus/Prothallium
flat.heart-shaped membranous structure with numerous rhizoids on its central lower surfaces.
Meiosis in seedless plants produces spores, which are haploid reproductive cells that can grow into multicellular haploid organisms called gametophytes. These gametophytes eventually produce gametes for sexual reproduction.

Ferns reproduce using sori and prothallus.

One sporophyte developes from one prothallus
The plant that reproduces using sori and a prothallus is a fern. Sori are clusters of sporangia where spores are produced, while prothallus is the gametophyte stage in the fern life cycle where fertilization occurs. Ferns have a unique reproductive cycle that involves both sexual and asexual reproduction.

Gametophyte generation of fern is called prothallus.
