A sporophyte is formed from the union of the nuclei of male and female reproductive cells, and each of its cells has two sets of chromosomes. In nonvascular plants, such as the mosses and liverworts, the sporophyte is a small plant or a part that grows on top of the gametophyte. In vascular plants, such as the ferns, grasses, conifers, and flowering plants, the sporophyte is the main form of the plant. Compare gametophyte.
Spores are haploid reproductive cells. Remember, a sporophyte is a diploid organism, so in order to produce haploid cells with half the number of chromosomes, meiosis must occur. Meiosis is a type of cell division that cuts the number of chromosomes in a cell in half. In sporophytes, it occurs in structures called sporangia (sporangium is singular). Once spores are produced in a sporangium, they are often released into the air. A single haploid spore will undergo mitosis, or cell division without a reduction in chromosome number, to become a multicellular haploid gametophyte.
