Question

What is the correct sequence of sperm formation?
A. Spermatid → spermatocyte → spermatogonia → spermatozoa
B. spermatogonia→ spermatocyte→ spermatozoa→ Spermatid
C. spermatogonia→ spermatozoa→ spermatocyte→ Spermatid
D. spermatogonia→ spermatocyte→ Spermatid→ spermatozoa

Answer 1

Hint:- The process by which the haploid spermatozoa is developed from germ cells is called
as Spermatogenesis. The spermatozoon is said to be a highly modified cell. It has three sections
which include a head, a midpiece filled with mitochondria which helps to cover the needs of the
cell’s energy, and a filamentous tail for the purpose of locomotion. The head of the spermatozoon is said to contain the cell nucleus and it is capped by an acrosome.

Complete step-by-step solution:-
The spermatozoa are produced by the mitosis and meiosis division of male primordial germ cells in
the process of spermatogenesis. The spermatogonia are said to be the initial cell that normally
produces the primary spermatocytes by the process of mitosis. It is said that the primary
spermatocyte divides meiotically (meiosis I) into two secondary spermatocytes. Also, every
secondary spermatocyte divides into two spermatids by Meiosis II. The sperm cells is the name given
to the mature spermatozoa. The secondary spermatocytes and the two secondary spermatocytes
are the two cells given rise by the primary spermatocyte by their subdivision produce four
spermatozoa.
Thus, the correct option is ‘spermatogonia→ spermatocyte→ Spermatid→ spermatozoa.’

Note:- The haploid male gamete that results from the division of secondary spermatocytes is called the spermatid. Each spermatid contains only half of the genetic material present in the original
primary spermatocyte as the result of the process of meiosis. Thus, we can say that a cell that is
produced at the second stage in the formation of spermatozoa is called spermatocyte. It is formed
from a spermatogonium and is divided by the process of meiosis into spermatids.
