- Sperm cell stained by Giemsa was clearly seen with mauve edge of cell membrane.The immature sperm cell was stained lighter than mature ones. 結果表明，用姬姆薩原液染色鑒定，精子形態(tài)清晰，細胞膜邊緣清楚，呈紫紅色，未成熟精子的染色程度淺于成熟精子；
- He has a low sperm count, ie He has few sperm cells and so is not very fertile. 他的精液中精子含量少.
- Before the discovery of the egg cell, many scientists believed that the head of each sperm cell contained a fully “preformed” little person (homunculus). 在卵細胞發(fā)現之前，許多科學(xué)家相信精子細胞的頭部含有一個(gè)全部的“預成型的”小人（矮人）。
- One secondary spermatocyte divides and eventually grows into two sperm cells. 一個(gè)次級精母細胞分裂并最終產(chǎn)生兩個(gè)精子。
- Sperm cells are produced in the male gonads or sex glands (testicles). 精子在男性生殖腺或性腺（睪丸）內產(chǎn)生。
- But undeveloped male sperm cells, called spermatogonia, do fine in a freezer. 但未發(fā)育的雄性精子細胞，即精原細胞，能夠較好的冷凍保存。

- We focused on several key events during fertilization from membrane fusion to karyogamy of sperm cells and egg cells. 探討了從精細胞和卵細胞質(zhì)膜融合到它們的核融合完成這一發(fā)育階段的某些主要事件。
- Not all bacterium have flagella and no human cells have them besides sperm cells. 并不是所以的細菌都有鞭毛，而人體細胞除了精子外也沒(méi)有鞭毛。
- What is known is that as men age, their ability to repair faulty DNA in sperm cells decreases. 大家都知道隨著(zhù)年齡的增加，精子細胞修復DNA錯誤的能力相應減弱。
