Sperm has enzymes that breakdown the outer coat of the oocyte. It takes many sperm with all their enzymes working together to accomplish this.

What does the sperm cell use to penetrate the egg?
The sperm structure containing enzymes to break down the egg's protective coating is called the Acrosome.
What is the difference between ovum and secondary oocyte?
ovum is the product after the secondary oocyte fuses with sperm
What destroys the sperm receptors on the surface of oocyte?
zonal inhibiting proteins
Sperm and ova are gametes?
Both are types of cells. The sperm cell carries the male's genetic contribution. The oocyte is the cell that carries the female's contribution. When the sperm cell meets the oocyte, the result is a fertilized human egg.
What would happen if more than one sperm were able to fertilize an egg?
The fact that only one sperm can fertilize an egg. After the sperm enters the cytoplasm of the oocyte, the cortical reaction takes place, preventing other sperm from fertilizing the same egg

Do females get nutrients from male sperm?
No, sperm are small packets of genetic material designed to fertilize an oocyte in the female reproductive tract. In fact, the sperm have just enough resources to get to the oocyte - the oocyte must supply much of the energy and resources necessary to complete fertilization. However, if a female were to ingest sperm, the female's digestive tract would break the sperm down into component amino acids which would provide minimal nutrients to the female.
What does the joining of the chromosomes of a sperm with those of an oocyte initially form?
A single cell is formed
What kind of gametocype is 'oocyte'?
"Oo" is the prefix for "egg" and "cyte" is the suffix for "cell," so an "oocyte" is an egg cell. It is the fundamental female sex cell, complementary to the male sperm.
Which component is vital for sperm to be able to penetrate the layers surrounding the egg?
The shape of the sperm is a component needed in order for the sperm to penetrate the layers surrounding the egg. Each sperm needs a head, tail, and mid-piece.
When does an oocyte complete meiosis II?
Meiosis II is completed after entry of sperm.
Can sperm penetrate cotton?
No. It does not have strong enough 'swimming' capabilities to penetrate clothing, including cotton.
How fertilization occurs?
One sperm cell must find the egg cell (oocyte) and penetrate the cell membrane. Only the head gets in. It (consisting almost entirely of DNA) is drawn to the nucleus of the egg cell where the chromosomes match and mix.
Can sperm penetrate through cotton?
No. It does not have strong enough 'swimming' capabilities to penetrate clothing, including cotton.
Which type of cell is produced by meiosis in a male organism?
Secondary spermatocyte
