Explanation:
A cell membrane is a semi-permeable membrane which acts as a barrier and a gatekeeper in that cell that allows some molecules to diffuse across while preventing others.Hydrophobic molecules that are small enough and gases pass across this membrane while larger molecules such as ions, sugar and amino acid are restricted to pass.Small polar molecules such as water also have there way past this membrane.

The structure of the mature sperm contains a tail, middle section having mitochondria and a head part. The tip of the head part contains <u>acrosome </u>and nucleus. The sperm at maturity, contains a cap like structure at the anterior end. It is termed as acrosome. In this structure, enzymes are present which help the sperm to penetrate into the egg for fertilization. The acrosome allows the plasma membranes of both the cells to fuse and fertilization takes place.
