The sperm contains

416
Sperm is the male reproductive cell , or gamete , in anisogamous forms of sexual reproduction forms in which there is a larger, female reproductive cell and a smaller, male one. Animals produce motile sperm with a tail known as a flagellum , which are known as spermatozoa , while some red algae and fungi produce non-motile sperm cells, known as spermatia. Sperm cells form during the process known as spermatogenesis , which in amniotes reptiles and mammals takes place in the seminiferous tubules of the testes. The spermatocytes then undergo meiosis , reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, which gives rise to the mature, motile sperm cell. This whole process occurs constantly and takes around 3 months from start to finish.

Sperm - Wikipedia

The mature sperm cell spermatozoa is 0. It consists of a head, body and tail. The head is covered by the ac cap and contains a nucleus of dense genetic material from the 23 chromosomes. It is attached from the neck to the body containing mitochondria that supply the energy for the sperm's activity. The tail is made of protein fibers that contract on alternative sides, giving a characteristic wavelike movement that drives the sperm through the seminal fluid, which also supplies additional energy.
