Question

The tubules are the site of sperm production, a process known as ____________ .The stem cells, called ____________ , contain 46 chromosomes.

Answer 1

Answer:

Spermatogenesis , Spermatogonia

Explanation:

Gonads are the primary sex organs in the male which are the two testes.

Each testis divide into testicular lobules each containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.

The process is known as spermatogenesis.

This process begins with mitotic division of stem cells which are located close to basement membrane of tubules. The cells are known as spermatogonial stem cells. The division produces two types of cells.

Type A cells are the cells which replenish stem cells and type B cells are the cells which differentiate into spermatocytes. They have number of chromosomes = 46.
