Final answer:
Spermatogenesis is the process of sperm cell production, which involves cell division and meiosis. It occurs in the testes and starts with spermatogonia dividing into primary spermatocytes at puberty. The end result is the production of mature sperm cells.
Step-by-step explanation:
Spermatogenesis is the process by which sperm cells are produced. It occurs in the wall of the seminiferous tubules in the testes. At puberty, spermatogonia undergo cell division to produce primary spermatocytes, which then go through meiosis to produce secondary spermatocytes and eventually spermatids. These spermatids mature into sperm cells.
