Question

Draw the diagram of human sperm and label its parts. Write few lines about it.

Answer 1

The sperm cells are the haploid gametes which are produced in the male. There are different parts of the sperm cell.
(a) Acrosome: This structure contains enzymes used for penetrating the female egg.
(b) Nucleus: There is the genetic material which is a haploid genome because it contains only one copy of each chromosome.

(c)Middle piece: The middle piece has a central filamentous core with many mitochondria spiralled around it which is used for ATP production for the journey through the female cervix, uterus and uterine tube.

(d) Tail: There is a long tail which is used for swimming and reaching near the egg.
