    Sperm

    Sperm, also known as spermatozoon, is a male reproductive cell. Sperm cells are formed during a biological process known as spermatogenesis which includes meiosis during which the chromosome number is cut in half. In most animals, sperm cells develop a tail known as flagellum which allows mobility. When a sperm cell fuses with an egg cell, a female reproductive cell, during fertilization, a new organism develops.
