Web26 Sep 2024 · Sporophytes in land plants In these plant species, the life cycle is formed by an alternation of generations: from diploid sporophyte to haploid gametophyte. When the male gamete and the female gamete unite and fertilization occurs, a diploid cell called the zygote is created, which regenerates the generation of sporophytes. moist sugar free banana bread
