The sperms are minute,microscopic and motile reproductive cells. They have an oval head piece, a neck, a middle piece and a long tail. Head piece consists of a large haploid nucleus. A sac like structure Acrosome is present in head piece which helps in fertilization. Middle piece has several mitochondria, which produce energy required for the movements of tail. Sperms live for a period of 24 to 72 hrs in the female reproductive system and afterwards they die and degenerate. Now lets draw a typical sperm cell.
Draw a oval shape and make a wavy line as shown.
Make Neck and middle piece and tail along the line.
Draw several mitochondria inside middle piece as shown.
Now neatly label the parts as shown above.
