Seed Plants. The sporophyte is also the dominant generation in seed plants. Seed plants are vascular plants that produce seeds and include some nonflowering plants (like pine trees) and flowering plants (like oak trees and roses). So when you see any of these plants, you are looking at the sporophyte. sporophyte is created by sexual reproduction of the gametophyte generation. Gametophytes make haploid unicellular gametes, or sperm and eggs. When a sperm cell fuses with an egg cell this is called fertilization. It creates a unicellular diploid zygote.
All pteridophytes have a true alternation of generations, in which a dominant sporophyte generation produces spores through meiosis, and a free-living gametophyte generation forms gametes (egg and sperm) by mitosis. Ferns can be used to illustrate the life cycle stages common to all pteridophytes.ern leaves used in floral arrangements are a major industry in Florida, and in some cultures tree fern stems are used to make elegant, naturally sculpted bowls. The contrasting colors of the vascular tissue in the stems and leaf bases of these plants create complex and pleasing designs.
