spermatid
sper·ma·tid / ˈspərməˌtid/ • n. Biol. an immature male sex cell formed from a spermatocyte that can develop into a spermatozoon without further division.DERIVATIVES: sper·ma·ti·dal / ˌspərməˈtīdl/ adj.
spermatid
spermatid One of four haploid cells formed during the second reduction-division of meiosis in male animals. Without further division they undergo cytoplasmic changes and condensation of the nucleus to give rise to spermatozoa. This process is called spermiogenesis.
spermatid
spermatid A nonmotile cell, produced during spermatogenesis, that subsequently differentiates into a mature spermatozoon. Four spermatids are formed after two meiotic divisions of a primary spermatocyte and therefore contain the haploid number of chromosomes.
