The sperm cells are very small, only about .05 mm long, they are only that longbecause of its long tail like flagella. Compared to the egg, one sperm volume is much less than the egg’s volume. The shape of the sperm has a small ovular head, connected to a long tail by a small part called the body. The function of the sperm is single minded. When ejaculated, they are supposed to swim as fast as possible to the egg in the fallopian tube, where it then penetrates the outer part of the egg in order to start the meiosis process and create a unique individual of the two gene donors. The sperm is half of what is needed for reproduction in order to continue the human race. The tail of the sperm cell is a modified flagella, which is used as a propeller for the sperm to swim towards the egg. The head is a spherical shape consisting of a large nucleus and a dome shaped acrosome.The acrosome releases a hyaluronidase enzyme. Sperm cells are not any of the four tissue types. It is a special exception.
