It has the same structure as the mature parental centriole , but is only about half its length .
它同成熟的父代中心粒有相同的结构,但仅仅是父代中心粒长度的一半.
It plays no role in the next mitosis , but becomes a parental centriole when it is distributed to one of the daughter cells .
在下一个有丝分裂中它不起作用,但是成为了一个父代中心粒,这时它被分配到子细胞的一个中去.
The centriole lies outside the nucleus of animal cells and many fungal and protoctist cells , but is absent in cells of most higher plants .
中心粒存在于动物细胞和许多真菌及原生生物的细胞核外，但在大多数高等植物中缺失。
However , the centriole is not essential for spindle formation , although an analogous structure , the basal body , is responsible for organizing the microtubules of undulipodla .
