When does the secondary oocyte complete its second meiotic division to become a mature ovum?
The secondary oocyte completes its second meiotic division upon fertilization by a sperm cell. This leads to the formation of a mature ovum and a polar body.
What structure expels the mature ovum?
The mature ovum is expelled from the ovary through a process called ovulation. The ovum is released from a mature ovarian follicle and enters the fallopian tube, where it can be fertilized by sperm.
During cytokinesis in a female what divides unequally?
During cytokinesis in a female, the cytoplasm divides unequally, resulting in one large cell (the secondary oocyte) and one small cell called the polar body. This unequal division helps ensure that the secondary oocyte retains most of the cytoplasm and organelles needed for further development, while the polar body eventually disintegrates.
What is another name for an immature egg cell?
gametes, sex cells, haploid cells. the process is meiosis.
When does meiosis 2 occur in females during the reproductive process?
Meiosis 2 occurs in females during the reproductive process after fertilization, when the secondary oocyte completes its division to form a mature ovum and a polar body.
