Fern gametophyte vs sporophyte
In all plants and some algae, an alteration of generations exists in which the species have diploid and haploid phases. Sexual reproduction results in gametes that combine two cells from different individuals. Meiosis also produces gametes. Haploids contain one set of chromosomes in each of their cells. … See more Sporophytes are diploid plants that use meiosis to produce spores.
