1.	(a) When and where does spermatogenesis occur in human male ? (b) Draw a diagram of a mature human male gamete ,Label the following parts : acrosome, middle piece and tail mention the function of acrosome and middle piece
Answer» (a) In tests , the immature male germ (spermatogonia) produce sperms by spermatogenesis that begin at puberty. (b) See Q.29,(or) Set-III , Delhi Board-2009 Functtion of acrosome: A plasma members envelops the whole body of sperm . The sperm head contains an elongated haploid nucels , the anterior portion of which is covered by a cap-like structure called acrosome . The acrosome is filled with enymes that help fertilise te ovum . Funcultion of middle piece : Middle piece dcontains a number of mitochondria , that provide energy for the motility of sperms.
