Spermatids

基本解釋

A single centriole appears at the late stage of spermatid.
晚期精細(xì)胞中出現(xiàn)單個(gè)中心粒，但在成熟精子中消失。
The tail emerged in the following stage in spermatid phase.
初級精母細(xì)胞略小，染色質(zhì)開始凝集，次級精母細(xì)胞開始出現(xiàn)尾部。
The early spermatid is small with an oval shaped nucleus.
結(jié)果顯示：早期精細(xì)胞圓形，胞質(zhì)豐富，內(nèi)含大量內(nèi)質(zhì)網(wǎng)小泡及線粒體。
Spermatocytes produced by mitosis in spermatogonia divide meiotically to generate haploid spermatids.
精原細(xì)胞經(jīng)有絲分裂再減數(shù)分裂產(chǎn)生單倍體精子細(xì)胞，即精母細(xì)胞。
As spermatid nucleus elongates, the chromatin fibers are unwound and join together to form ribbon structure.
當(dāng)精細(xì)胞核向長形轉(zhuǎn)變時(shí),染色質(zhì)纖維解旋并結(jié)合在一起形成緞帶結(jié)構(gòu)。
