primary spermatocyte

spermatocyte

 [sper-mat´o-sīt]
the mother cell of a spermatid.
primary spermatocyte the original large diploid cell into which a spermatogonium develops; it can later undergo the first meiotic division into the secondary spermatocyte.
secondary spermatocyte a haploid cell produced by meiotic division of the primary spermatocyte; it can then develop into the spermatid.

pri·mar·y sper·ma·to·cyte

the spermatocyte derived by mitotic division from a spermatogonium, and that undergoes the first division of meiosis.

pri·mar·y sper·ma·to·cyte

(prī'mar-ē spěr-mat'ŏ-sīt)
The spermatocyte derived by a growth phase from a spermatogonium; undergoes the first division of meiosis.

primary spermatocyte

an early stage in SPERMATOGENESIS.

spermatocyte

the mother cell of a spermatid.

primary spermatocyte
daughter cell of a spermatogonium (an incongruous nomenclature in such an intensely masculine context). It undergoes the first meiotic division.
secondary spermatocyte
a cell produced by meiotic division of the primary spermatocyte, and which gives rise to the spermatid.
