Comment
Pollen sperm cells are structurally simple, usually non-motile cells that may contain a normal complement of cellular organelles, including heritable cytoplasmic organelles such as mitochondria and, in some plants, plastids, but lack a cell wall. In seed plants, pollen sperm cells are usually two in number. In angiosperms, during double fertilization, one fuses with the plant egg cell (PO:0020094) to produce a plant zygote (PO:0000423) while another fuses with the two polar nuclei of the embryo sac central cell (PO:0020090) to give rise to endosperm (PO:0009089). In angiosperms, the pollen sperm cell arises from the generative cell (PO:0020097). In gymnosperms, the pollen sperm cell arises from the body cell (PO:0025525).
