Spermatogenesis is the production of sperm from the primordial germ cells. It takes place in the seminiferous tubules of the testes.
- Germinal epithelium cells form spermatogonia (singular: spermatogium).
- Spermatogonia undergo a period of growth and maturation, dividing many times via mitosis to produce primary spermatocytes.
- Primary spermatocytes undergo meiosis and the products of this first meiotic division are haploid secondary spermatocytes.
- Secondary spermatocytes undergo and second meiotic division and produce spermatids.
- These then differentiate, mature and become spermatozoa (singular: spermatozoon), or what you normally call sperm.
Spermatogenesis involves meiosis, mitosis, growth and maturation. State which of these processes is involved in each of the following steps in spermatogenesis. a) Spermatogonium to primary spermatocyte; b) Spermatid to spermatozoan (sperm).
Spermatogenesis takes place in the seminiferous tubules, in the testis. State whether each of the following cells is haploid or diploid: a) spermatogonium; b) primary spermatocyte; c) secondary spermatocyte; d) spermatid; e) spermatozoan.
