From the following options, identify the cells in which mitosis occurs.
From the following options, identify the cells in which mitosis occurs.
The correct option is D Primordial germ cells
The process of the formation of haploid gametes from the undifferentiated diploid germ cells in the gonads for sexual reproduction is called gametogenesis. In the case of males, it is spermatogenesis.
The process of the formation of sperm/spermatozoa in seminiferous tubules of the testis is called spermatogenesis. It involves three phases - multiplication, growth and maturation phase. In the multiplication phase, spermatogenic cells or primordial germ cells, by the process of mitosis, produce a large number of diploid spermatogonia or sperm mother cells. In the growth phase, spme spermatogonia increase their size by the accumulation of cytoplasm and replication of DNA. They are termed as primary spermatocytes (2n). Each primary spermatocytes (2n) undergoes two successive maturation divisions (i.e., meiosis I and meiosis II) leading to the formation of haploid spermatids (n).
Spermatids by the process of spermiogenesis, transform into spermatozoa (n). After spermiogenesis, heads of the sperms are embedded in the Sertoli cells and are finally released from the seminiferous tubules by the process of spermiation.
