Draw a diagram of mature human sperm. Label any three parts and write their functions.

The sperm is divided into three parts Head, Middle piece, and Tail. The functions of different parts of the sperm are mentioned below: Head: The anterior part of the sperm is the head. It consists of an acrosome at its tip and a haploid nucleus is present behind it. Middle piece: The region below the head is the middle piece. This region is rich in mitochondria. Mitochondria provide the necessary energy in the form of ATP to the sperm for motility. Tail: This is the last part of the sperm. It is flagellar in nature, due to which it can propel and move forward in the female reproductive system.
