n. pl sperm
A Closer Look: The human sperm cell is divided into a head that contains the nucleus, a mid-section that contains mitochondria to provide energy for the sperm, and a flagellum that allows the sperm to move. When fertilization occurs, the nucleus and other contents from the sperm cells are drawn into the cytoplasm of the egg, but the mitochondria in the sperm are destroyed and do not survive in the zygote. Since mitochondria contain their own DNA (thought to be a relic from an existence as separate symbiotic organisms), all of the mitochrondrial DNA in humans is thus inherited from the female. The semen produced by the male reproductive tract as a medium for sperm typically contains over 100 million sperm cells, all of which have but one purpose: to fertilize the single available egg.
