Primary spermatocyte differs from spermatogonium in

Primary spermatocyte differs from spermatogonium in size and volume. In testis, the immature male germ cells, spermatogonia produce sperms by a process called spermatogenesis that begins at puberty. It occurs in four stages. During the first step of spermatogenesis, i.e. spermatocytogenesis, the spermatogonia present on the inside wall of the seminiferous tubules multiply by mitotic division and increase in numbers. Each spermatogonia is diploid containing 46 chromosomes. When spermatogonia accumulate a large amount of nutrient and chromatin material and increases in size, it is known as primary spermatocytes. It periodically undergoes meiosis and others remain as spermatogonia cells. A primary spermatocyte is diploid, (2n) with 44+XY (total 46) chromosomes.
