1.	When and Where does spermatogenesis occur in human male ? (b) Draw a diagram of a mature human male gamete. Label the following parts: acrosome, nucleus, middle piece and tail. (c) Mention the functions of acrosome and middle piece.
Answer» In testes, the immature male germ cells (spermatogonia) produce sperms by spermatogenesis that begin at puberty (c) Function of acrosome : 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 called acrosome. The acrosome is filled With enzymes that help fertilise the ovum. Function of middle piece : Middle piece contains a number of mitochondria, that provide energy for the motility of sperms.
