Describe the structure of a mature human sperm.

A sperm has a head, a middle piece and a tail. The head holds the haploid nucleus capped by the acrosome, which carries the enzymes that dissolve the egg coverings. The middle piece is packed with mitochondria that supply the energy for movement, and the tail propels the sperm.

No citable source has been recorded for this record. Treat it as practice material, not as fact.

Explanation

The whole cell is covered by a plasma membrane.
