As spermatogenesis takes place, each cell division moves the sperm closer to the exterior wall of the seminiferous tubule.
Group of answer choices
- True
- False
Solution
Answer
True
Spermatogenesis is the process by which sperm cells are produced in the testes. It occurs within the seminiferous tubules, which are the site of sperm maturation. During this process, germ cells undergo several stages of division (mitosis and meiosis) and differentiation.
As the cells divide and differentiate, they move closer to the lumen (interior) of the seminiferous tubule. Initially, spermatogonia, which are the stem cells, are located at the basement membrane. As they undergo division and maturation through primary spermatocyte and secondary spermatocyte stages to ultimately form spermatids, they migrate toward the tubular lumen. Hence, as spermatogenesis progresses, each cell division indeed moves the developing sperm cells closer to the exterior wall of the seminiferous tubule.
