Question
In which cell does the first meiotic cell division take place during the process of spermatogenesis?
The correct answer is
Primary spermatocyte
Spermatogenesis: Meiosis I Location
Spermatogenesis is the process of sperm cell formation. It involves both mitosis and meiosis.
- Spermatogonia (diploid stem cells) divide by mitosis to produce more spermatogonia and primary spermatocytes.
- Primary spermatocytes (diploid) are the cells that enter the first meiotic division (Meiosis I).
- Meiosis I separates homologous chromosomes, resulting in two secondary spermatocytes (haploid).
- Secondary spermatocytes then undergo the second meiotic division (Meiosis II), separating sister chromatids to form spermatids.
- Sertoli cells are somatic cells supporting spermatogenesis but do not undergo meiosis.
Therefore, the first meiotic cell division occurs specifically in the primary spermatocyte.
