The process whereby the generative cell divides by mitosis to form two haploid cells. These will subsequently differentiate into sperm cells. The process, occurring above the cellular level, that is pertinent to the reproductive function of a multicellular organism. This includes the integrated processes at the level of tissues and organs. The regular alternation, in the life cycle of haplontic, diplontic and diplohaplontic organisms, of meiosis and fertilization which provides for the production offspring. In diplontic organisms there is a life cycle in which the products of meiosis behave directly as gametes, fusing to form a zygote from which the diploid, or sexually reproductive polyploid, adult organism will develop. In diplohaplontic organisms a haploid phase (gametophyte) exists in the life cycle between meiosis and fertilization (e.g. higher plants, many algae and Fungi); the products of meiosis are spores that develop as haploid individuals from which haploid gametes develop to form a diploid zygote; diplohaplontic organisms show an alternation of haploid and diploid generations. In haplontic organisms meiosis occurs in the zygote, giving rise to four haploid cells (e.g. many algae and protozoa), only the zygote is diploid and this may form a resistant spore, tiding organisms over hard times. Generation of the male gamete; specialised haploid cells produced by meiosis and along with a female gamete takes part in sexual reproduction. The process whereby a relatively unspecialized cell acquires specialized features of a haploid sperm cell within the plant gametophyte. The generation and maintenance of gametes in a multicellular organism. A gamete is a haploid reproductive cell. The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.
