When fertilasation happens the nucelues of the sperm must?
When fertilisation happens the nucleus of the sperm cell must release a special chemical which helps it to find a way into the ovum (egg).By Sophie Tyler On The 20/3/2010.
What are 3 parts of the sperm?
Each sperm cell has three parts: a head, middle piece, and tail. An acrosome at the head tip produces enzymes that help penetrate the female ovum (egg). During conception, chromosomes (genetic material) in the nucleus (cell control center) join with chromosomes in the ovum. The middle piece contains mitochondria, structures that provide energy for the sperm. The mitochondria are tightly spiraled around the axial filaments (contractile portion) of the flagellum (tail). Centrioles form the tail, which moves the sperm toward the ovum. An ejaculation (ejection of sperm from the penis) has 300 to 500 million sperm. http://www.besthealth.com/besthealth/bodyguide/reftext/html/repr_sys_fin.html
