Solution
The correct option is D Mitochondria
A sperm is composed of a head, neck, a middle piece and a tail. A plasma membrane envelops the whole body of sperm. The sperm head contains an elongated haploid nucleus, the anterior portion of which is covered by a cap-like structure, acrosome. The acrosome is filled with enzymes, that help in fertilization of the ovum. The middle piece possesses numerous mitochondria, which produce energy for the movement of a tail, that facilitate sperm motility essential for fertilization. The human male ejaculates about 200 to 300 million sperms during a coitus of which, for normal fertility, at least 60 percent sperms must have normal shape and size and for at least 40 percent of them must show vigorous motility.
