What is the difference between spermatogonia and spermatogenesis?
Sperms are the male gametes produced in the seminiferous tubules of the testes. The main difference between spermatogenesis and spermiogenesis is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the maturation of the spermatids into sperm cells.
What is the process of spermatogonia?
Spermatogenesis is the process of sperm cell development. Rounded immature sperm cells undergo successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa. Mitosis and meiosis.
What is spermatogonia and its function?
A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell. Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testis. Spermatogonium. Germinal epithelium of the testicle.
Which type of spermatogonia turns into sperm?
The primary spermatocyte divides meiotically (Meiosis I) into two secondary spermatocytes; each secondary spermatocyte divides into two equal haploid spermatids by Meiosis II. The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis….

What is the stages of spermatogenesis?
The process of germ cell development during spermatogenesis can be divided into five succesive stages: (1) spermatogonia, (2) primary spermatocytes, (3) secondary spermatocytes, (4) spermatids, and (5) spermatozoa.
What are the steps of spermatogenesis?
There are three steps in spermatogenesis: 1) meiosis, during which the number of chromosomes in the cell is reduced to half or 23 chromosomes each; 2) meiosis II, during which each haploid cell forms spermatids; and 3) spermiogenesis, during which each spermatid develops into a sperm cell with a head and tail.
What are spermatogonia quizlet?
spermatogonia. (aka germ cells; stem cells) diploid cells located within the seminiferous tubules that serve as a reservoir of cells that will eventually undergo meiosis to produce immature germ cells, the spermatids. primary spermatocytes.
What are the types of spermatogonia?
In human, there are only two different types of A spermatogonia, the Adark and Apale spermatogonia. The Adark spermatogonia are considered reserve stem cells, whereas the Apale spermatogonia are the self-renewing stem cells.
Where are spermatogonia located?
the testis
They derive from immature germ cells called spermatogonia. They are found in the testis, in a structure known as the seminiferous tubules. There are two types of spermatocytes, primary and secondary spermatocytes. Primary and secondary spermatocytes are formed through the process of spermatocytogenesis.
When spermatogonia divide the daughter cells are called?
Spermatogonia divide by mitosis and one daughter cell becomes another spermatogonium and one becomes what’s called a PRIMARY SPERMATOCYTE. This cell is now more specialized than the spermatogonium. It is a diploid cell (2n). Primary spermatocytes grow for a while and then undergo meiosis.
How does spermatogonia become primary spermatocyte?
Key Points. Spermatogenesis begins with a diploid spermatogonium in the seminiferous tubules, which divides mitotically to produce two diploid primary spermatocytes. The primary spermatocyte then undergoes meiosis I to produce two haploid secondary spermatocytes.
What are the events in spermatogenesis?
Spermatogenesis can be divided into three phases: (1) proliferation and differentiation of spermatogonia, (2) meiosis, and (3) spermiogenesis, a complex process that transforms round spermatids after meiosis into a complex structure called the spermatozoon.
