Final answer:
From each primary spermatocyte, four sperm cells are produced through a process known as spermatogenesis. This occurs in the seminiferous tubules of the testes and includes two rounds of meiosis.
Step-by-step explanation:
The process through which sperm are produced from a primary spermatocyte is known as spermatogenesis. This biological process occurs in several stages within the walls of the seminiferous tubules of the testes. Initially, a spermatogonial stem cell undergoes mitosis to produce two diploid daughter cells called primary spermatocytes. As spermatogenesis continues, each primary spermatocyte undergoes meiosis I to produce two haploid cells known as secondary spermatocytes. These secondary spermatocytes then rapidly go through meiosis II to produce a total of four haploid daughter cells called spermatids. Eventually, these spermatids grow a flagellum and mature into sperm cells. Therefore, from each primary spermatocyte, four sperm are eventually produced.
