Draw a schematic diagram of a human sperm and label the cellular components. Give the functions of any three parts.
Where are the sperm heads found embedded to survive after spermiogenesis?

Explanation

Head : The acrosome contains hydrolytic enzymes which dissolves the egg membrane for fertilisation.
Middle piece : It contains mitochondria that provide energy for the movement of the sperms.
Tail: It helps in the motility of sperms that helps for the swimming of sperms in a liquid medium.
The sperm head becomes embedded in the Sertoli cells : See Q.19.,Delhi Board, Set-I,2008.
