Explanation:
The major parts of a mature spermatozoan in human males are the head, middle piece and the tail. The head of the sperm is a flattened and pointed structure that contains a nucleus. There are 23 chromosomes present in the nucleus. Chromosome surrounds the anterior two-thirds of the nucleus. The acrosome is a caplike vesicle and is filled with hydrolytic enzymes that help a sperm during fertilization. The middle piece contains mitochondria that provide the energy (ATP) for locomotion of sperm to the site of fertilization and for sperm metabolism.
