What else can I help you with?
What layers do sperm penetrate to fertilize the oocyte?
Sperm penetrate through the zona pellucida, an acellular glycoprotein layer surrounding the oocyte, to reach the oocyte membrane for fertilization. The sperm then binds to specific receptors on the oocyte membrane to release enzymes that help in penetrating the oocyte membrane to fuse with the oocyte.
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 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.
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
How many eggs are in a human egg cell?
One. A cell cannot consist of multiple things. It is a complete unit.
What cell can you see with your own eyes?
the Oocyte is the largest human cell and can be seen by the naked eye. more information on the Oocyte: http://en.wikipedia.org/wiki/Oocyte

In which stage is a primary oocyte arrested?
A primary oocyte is arrested in the prophase stage of meiosis I.
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
Is the human ovule an organ?
The human ovule is not an organ. It is a structure within the ovary that contains the female reproductive cell, the oocyte. The ovary itself is an organ, but not the ovule.
In what phase of meiosis is a secondary oocyte arrested?
A secondary oocyte is arrested in the metaphase II phase of meiosis.
At what stage of development does a secondary oocyte arrest in?
A secondary oocyte arrests in the metaphase II stage of development.
How many eggs are in a human egg cell?
One. A cell cannot consist of multiple things. It is a complete unit.
What has the author Eleonora Porcu written?
Eleonora Porcu has written: 'Handbook of human oocyte cryopreservation' -- subject(s): Oocytes, Cytology, Cryopreservation, Methods
What is the size of a polar body?
a polar body is A small cell (which eventually disintegrates) that is the by-product of meiosis in female animals. One functional ovum and potentially three polar bodies result from meiosis of each primary oocyte. By:hyden 252-1079 im bored
