In the life of plants there are two “generations,” the sporophyte and gametophyte generations. The gametophyte generation is the haploid while the sporophyte generation is diploid. In the life of a fern, after the zygote undergoes mitosis, the plant is now in the sporophyte part of its life. And during the mature part of the sporophyte generation, meiosis occurs to produces haploid spores. These spores are found underneath the “leaf” or frond of a fern. In the life of a fern, the sporophyte generation is longer that the gametophyte generation.
