What are the structure-functions of a sperm cell?
The sperm cell is an interestingly specialised cell whose function is to swim to the ovum and then to fertilise it. The sperm cell has three basic parts. The head contains the DNA to be injected into the ovum and also has chemotatic receptors for navigation towards the ovum. The Tail is at the other end and is a single flagella in healthy cells. This structure flips and twists in such a way as to propel the cell along. Finally between the two is the body of the cell which contains six mitochonria to power the movement of the flagella. It is the the joint between the body and the head that is broken during fertilisation so that none of the motochondria are from the father.
