Spermatid
The term spermatid refers to the haploid male germ cell that results from secondary spermatocyte division. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.
Spermatid
[Gr. spermatos - seed, semen]. Haploid cell in male testes, formed from spermatocyte by meiosis and will differentiate into a spermatozoon.
spermatid
[Gk. sperma, seed]
Each of four haploid (n) cells resulting from the meiotic divisions of a spermatocyte; each spermatid becomes differentiated into a sperm cell.

spermatid A growth stage of a male reproductive cell arising by division of a secondary spermatocyte; gives rise to a spermatozoon.
spermatium Minute, nonmotile male gametes that occur in the rust fungi.
Then the spermatids differentiate into sperm, losing most of their cytoplasm in the process.
The cell that undergoes meiosis is a primary spermatocyte. The first meiotic division produces two secondary spermatocytes and the second division produces spermatids, which mature to form sperm.
Most of these cells are in a condition of karyokinetic division, and the cells which result from this division form those of the next layer, the spermatoblasts or spermatids.
Seminiferous tubules are inside each testis, and are where sperm are produced by meiosis. About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn ...
