卵细胞

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

颈器)腹部：颈器内含有细胞(球)而向外膨大基部。

We focused on several key events during fertilization from membrane fusion to karyogamy of sperm cells and egg cells.

探讨了从精细胞和细胞质膜融合到它们核融合完成这一发育阶段某主要事件。

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、裂期胚胎质量关系。

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，次级母细胞又分裂成两个大小不对等新细胞：一个相对很大（成熟细胞）和一个微小次级极体。
