Description :
Sperms are minute, microscopic and motile in nature. Sperms are released from Testis. It has three parts namely, Head, Middle piece and a Tail .
* The head piece consists of a sack like structure called Acrosome. It helps the sperms in penetrating into Ovum during Fertilization. In the middle of the head male nucleus is present. It fuses with the female nucleus. Head and middle piece are attached by neck.
* Middle piece consists of several Mitochondria which gives energy for the movement of the sperm.
* The tail propels the sperm. Sperms have streamlined body which helps them to move quickly.
Sperm is a male representative cell and it is a specialized cell in that it had adaptation which help it to function effectively.
1. It has acrosome with a lytic enzyme which digest the egg membrane to allow it to penetrate into the nucleus of the ovum to allow fertilization.
2. It has many mitochondria to provide it with energy of movement.
3. It has a long tail to allow propulsion of the sperm from the vagina to the oviduct to allow fertilization to take place.
4. It has a nucleus which contains the genetic information.
I hope it is helpful to you.
