Given below is the diagram of a human sperm. Read the information below the diagram and fill in the blanks:

Living organisms reproduce to form new individuals of their own kind. This is essential for the survival and continuation of species. Human sperms are microscopic structures that carry genetic material.

The head of the sperm has a cap like organelle called (a) ______ (Lysosome/Acrosome) which produces an enżyme (b) ______ (Hyaluronidase/Amylase) that dissolves the outer layer of the ovum to facilitate fertilisation. The nucleus of the sperm has (c) ______ (23/46) chromosomes. The middle piece has (d) ______ (Chloroplast/Mitochondria) to provide energy for the motility of the sperm. (e) ______ (Semen/Hymen) is a mixture of sperms and the fluids produced by the male accessory glands.

Answer 1

The head of the sperm has a cap like organelle called Acrosome which produces an enżyme Hyaluronidase that dissolves the outer layer of the ovum to facilitate fertilisation. The nucleus of the sperm has 23 chromosomes. The middle piece has Mitochondria to provide energy for the motility of the sperm. Semen is a mixture of sperms and the fluids produced by the male accessory glands.
