How is a sperm cell adapted to it's role?

The role of the sperm cell is to fertilise the egg. It is adapted to fulfill this role in four main ways. Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.
