Question

The given below are the differences between spermatogenesis and spermiogenesis.
(a) Spermatogenesis- Process of formation of spermatozoa
Spermiogenesis- Process of differentiation of spermatozoa from a spermatid
(b) Spermatogenesis- It changes a diploid structure into a haploid structure.
Spermiogenesis- It involves the conversion of a haploid structure into another haploid.
(c) Spermatogenesis- growth and division occurs
Spermiogenesis- Divisions and growth are absent
(d) Spermatogenesis- A spermatogonium forms four spermatozoa
Spermiogenesis- A spermatid forms a single spermatozoan.

Answer 1

Hint: These are the methods of developing male gametes, referred to as sperm within the male reproductive organs, the testes. During this process, each sperm (haploid) contains one copy of every chromosome.

Complete answer:
Spermatogenesis includes the transformation of a diploid structure (spermatogonia) into haploid structures (spermatozoa). Spermiogenesis develops a haploid structure (spermatid) within another haploid structure (spermatozoon). Sperms are formed within the seminiferous tubules of the testes, the male reproductive organ. The formation of sperm may be a necessary step in reproduction. The mature sperm or spermatozoa are produced within the process, which carries genetic information from one generation to a subsequent generation.
Spermatogenesis is a process of gametogenesis in males. The male germinal cells or spermatogonia present in seminiferous tubules undergo proliferation by mitotic division. A number of the spermatogonia cells undergo meiotic division and are referred to as Primary spermatocytes (diploid). Secondary spermatocytes (haploid) are formed after the primary meiotic division of primary spermatocytes. Secondary spermatocytes support a second meiotic division producing four haploid spermatids. Spermiogenesis is the transformation of spermatids to mature sperm or spermatozoa. Spermiation is the process of release of mature sperms from seminiferous tubules.

So, the correct answer is ‘Spermatogenesis- It changes a diploid structure into a haploid structure. Spermiogenesis- It includes the conversion of a haploid structure within another haploid’.

Note:
Spermatogenesis starts at puberty in males. It gives rise to mature male gametes, which may undergo fertilization with an ovum to make a zygote. This process is extremely sensitive to changes in temperature, deficiency within the diet, alcoholism, and exposure to drugs, and therefore the presence of disease can affect the speed of sperm formation adversely.
