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

The sperm head contains an elongated haploid nucleus, the anterior portion of which is covered by a cap-like structure, acrosome. The acrosome is filled with enzymes that help fertilisation of the ovum.

Middle piece contain mitochondria which produce energy for the movement of the tail that facilitate sperm motility essential for fertilisation.

Tail of the sperm helps in the motility.
