Q2: Describe the maturation of spermatid into spermatozoon(sperm)..
cell differenciation takes place in the sertoli cells...where the sperm gets matured into spermatozoan..
a tail forms called flagellum and is made of microtubules..with many mitochondria..
and the head made of acrosome which contains hydrolytic enzymes..
