Question

Draw a diagram of mature human sperm. Label any three parts and write their functions.

Answer 1

The human sperm mainly consists of the head, neck, middle piece and tail. The tail helps in the movement of the sperm. The head contains a cap-like structure called the acrosome. The acrosome is filled with enzymes that help fertilisation of the ovum. The middle piece helps in the production of energy due to the presence of numerous mitochondria in it. This energy helps in sperm motility needed for fertilization.
