spermatid

spermatid

 [sper´mah-tid]
a cell produced by meiotic division of a secondary spermatocyte; it develops into the spermatozoon.

sper·ma·tid

(sper'mă-tid),
A cell in a late stage of the development of the spermatozoon; it is a haploid cell derived from the secondary spermatocyte and differentiates by spermiogenesis into a spermatozoon.
Synonym(s): nematoblast
[spermat- + -id (2)]

spermatid

/sper·ma·tid/ (sper´mah-tid) a cell derived from a secondary spermatocyte by fission, and developing into a spermatozoon.

spermatid

(spûr′mə-tĭd)
n.
Any of the four haploid cells that are formed by meiosis from a spermatocyte and that develop into spermatozoa without further division.

spermatid

[spur′mətid, spərmat′id]
Etymology: Gk, sperma, seed
a male germ cell that arises from a spermatocyte and becomes a mature spermatozoon in the last phase of spermatogenesis.

sper·ma·tid

(spĕr'mă-tid)
A cell in a late stage of the development of the sperm; it is a haploid cell derived from the secondary spermatocyte and evolves by spermiogenesis into a sperm.
[spermat- + -id (2)]

spermatid

a haploid stage in male GAMETO GENESIS.

spermatid

a cell produced by meiotic division of a secondary spermatocyte; it develops into the spermatozoon.
