卵细胞

Venter The swollen base of an archegonium that contains the egg cell (oosphere).

颈器)腹部：颈器有细胞(球)而向外膨基部。

Objective To investigate the relationship between the first polar body morphology of oocyte and the zygote morphology in pronucleus stage, embryo quality in cleavage stage.

目探讨细胞第一极体形态与原核期受精形态、期胚胎质量关系。

The secondary oocyte now divides again into two new cells of unequal size: a relatively large ootid (mature egg cell) and a minute second polar body.

此时，次级母细胞又分成两个小不对等新细胞：一个相对很子（成熟细胞）和一个微小次级极体。
