These stages, which were explained by Dr. Judith Sumner in the video, can be thought of as different "generations" within the same life cycle. The adult generation produces spores, while the spore ... Life scientists have developed several theories to account for the evolution of alternation of generations in plants.

The plant life cycle has an alternation between haploid (gametophyte) and diploid (sporophyte) generations. There are more than 300,000 living species of plants known, as well as an extensive fossil record.

Because of this, they, like the bryophytes, follow an alternation of generations life cycle. Unlike the bryophytes, however, the larger plant, the form we all think of when the word "fern" comes up, is the sporophyte.
