Question

Acrosome aids the sperm to
A) Penetrate the vitelline membrane of ovum
B) Find ovum
C) Swim
D) Higher activity

Answer 1

Hint: The acrosome is a spermatozoa organelle that grows over the anterior half of the brain. The acrosome reaction aids the sperms in breaking through the egg's protective coat.

Complete answer:
Option A Penetrate the vitelline membrane of the ovum: Acrosome aids the sperm to penetrate the vitelline membrane of the ovum. The function of acrosomes is to help the sperms to enter into the egg’s protective coat. And to follow the plasma membranes of sperm and egg to fuse.
Option A is correct Acrosome aids the sperm to penetrate the vitelline membrane of ovum
Option B Find ovum: Protein in the cell membranes of the sperm helps the sperms to find their way to eggs. Acrosomes do not aid the sperm to find the ovum. It aids to penetrate the vitelline membrane of the ovum.
Option C Swim: Sperm motility describes the ability of sperm to move properly through the female productivity tract. Sperm’s tail has a large number of proton channels called \[Hv1\] that respond to changes in \[pH\] and zinc level outside the cell. When the channel opens, a proton comes out of the sperm cells, causing the \[pH\] inside the cell to rise and the sperm to swim. The acrosome does not aid the sperm to swim.
Option D Higher activity: The function of the reproductive system depends on the general health of the body. Acrosomes do not aid sperm's higher activity.

Hence the correct answer is option A.

Note:
Acrosome aids the sperm to penetrate the vitelline membrane of the ovum. Acrosomes are the organelle that develops over the anterior half of the head in the sperm. Sperms have a cap-like structure. Acrosomes help the sperms to penetrate the egg.
