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.
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 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.
What is another name for an immature egg cell?
gametes, sex cells, haploid cells. the process is meiosis.
Describe the functions of the gonads?
The gonads are responsible for producing gametes (sperm in males, eggs in females) and sex hormones (testosterone in males, estrogen and progesterone in females). These hormones are important for sexual development, secondary sexual characteristics, and reproductive function.
When a primary oocyte divides a secondary oocyte and what are produced?
A primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte undergoes meiosis II to produce a mature ovum (egg) and another polar body.
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.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.
The cell commonly called the egg or ovum is more correctly called?
The egg or ovum is more correctly called an oocyte. It is referred to as an oocyte until it is fertilized by sperm, after which it becomes an embryo.
What is period of ovum?
an ovum mature oocyte after meiosis division
What is the period of ovum?
an ovum mature oocyte after meiosis division

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.
A single egg is called an?
A single egg is called an ovum or oocyte.
What is another name for an immature egg cell?
gametes, sex cells, haploid cells. the process is meiosis.
What is the female sex cell or egg is also called an?
The female sex cell or egg is also called an ovum or oocyte.
How many egg cells come form a female germ cell?
One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
