a male sex cell. It is formed during the production of sperm.
A cell undergoing meiosis to give rise to sperm cells.
The sperm cell equivalent to the oocyte stage of the egg. Further development in the testicular tubules results in a spermatid. See also: primary spermatocyte See also: secondary spermatocyte See also: spermatogenesis
a male gametocyte that develops into four spermatids
A cell from which 4 spermatids develop
Sperm cell that is immature. close window
Gr. spermatos - seed, semen; Gr. kytos - a hollow vessel; modern usage cyt- denotes a cell]. An immature diploid germ cell found in the testis that arose from a spermatogonium and that will undergo two meiotic divisions to become four spermatids.
A cell of the seminiferous tubules that is engaged in meiosis.
In nematodes: A cell giving rise to spermatozoa or spermatozooids. ( 18)
A spermatocyte is a male gametocyte which is derived from a spermatogonium. Initially, a spermatogonium divides by mitosis into two so-called primary spermatocytes. A primary spermatocyte is also diploid, and, in turn, gives place by meiosis to two secondary spermatocytes, which this time are haploid.
