Question

What surrounds a secondary oocyte?

Answer 1

Secondary oocyte:

1. A secondary oocyte is a resultant oocyte after meiosis I is done, and it gives birth to ootid and ovum (egg cell) when meiosis II is completed.
2. The secondary oocytes will be blocked at metaphase II of meiosis II until fertilization occurs.
3. The haploid secondary oocyte
4. When a sperm cell fertilizes a female sex cell, the secondary oocyte quickly completes the remaining steps of meiosis II, producing an ootid and an ovum with which the sperm cellmates.

Surrounding of secondary oocyte:

1. A layer of zona pellucida and corona radiata surrounds a secondary oocyte.
2. A glycoprotein coating that surrounds mammalian oocytes is known as the zona pellucida.
3. The zona pellucida exists between the oocyte plasma membrane and the corona radiata.
4. The Zona pellucida is essential for effective fertilization because it begins the acrosome response, which allows sperm to enter the secondary oocyte.
5. Corona Radiata refers to the many layers of granulosa cells that exist outside of the zona pellucida layer. A hyaluronic acid matrix holds these cells together.
