n.原核生物細(xì)胞

Prokaryote cells evolved first and gave rise to eukaryote cells. 原核細(xì)胞先產(chǎn)生，而后產(chǎn)生真核細(xì)胞。

Flagellum (pl. flagella) A whiplike extension of prokaryote cells, with a basal body at its base, whose beat causes locomotion of the cell. 鞭毛：原核細(xì)胞的鞭狀延長部分，基部有基體，當(dāng)鞭毛進(jìn)行揮鞭式運(yùn)動時可以促使細(xì)胞移動。

Eukaryotic cells are about 10 times the size of a prokaryote and can be as much as 1000 times greater in volume. 真核細(xì)胞比原核細(xì)胞大10倍，體積是原核生物的1000倍。

Plant pathogenic bacteria are tiny prokaryote with the characteristic of rapid propagation. 摘要植物病原細(xì)菌是寄生在植物上的原核生物，個體微小，繁殖速度快。

Prokaryote (prokaryote) An organism whose genetic material (DNA) is not enclosed by membranes to form a nucleus but lies free in the cytoplasm. 原核生物：指遺傳物質(zhì)（DNA）沒有被膜包圍形成細(xì)胞核，而是在細(xì)胞質(zhì)中游離存在的一類生物體。
