Question

How is a primary spermatocyte different from a secondary spermatocyte?

Answer 1

Hint: The main function of spermatocytes is to divide and produce immature sperm called spermatids. Secondary spermatocytes in meiosis II is the stage of special division where DNA is reduced to half.

Complete answer:
Spermatogenesis is the process of formation of sperms in the male reproductive system. It involves the process of meiosis. It initiates during puberty and occurs in seminiferous tubules. It goes through various phases and the primary spermatocyte and secondary spermatocyte are the results of the process of spermatogenesis. Spermatocytes produce spermatids which are called sperms. Sperms are the male gamete which fuses with the female gamete to bring a new life. Spermatogenesis begins with a diploid (2n) spermatogonia in the seminiferous tubules, which divides mitotically to produce two diploids (2n) primary spermatocytes. The primary spermatocyte then undergoes meiosis I to produce two haploid secondary spermatocytes. Primary spermatocytes are diploid (2N) cells. Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes. This is the major difference between primary and secondary spermatocytes. All male animals produce spermatocytes, including hermaphrodites such as C. elegans. InC. elegans, sperm production occurs first and then it is stored in the spermatheca.

Note: The condition in which males cannot produce sperms is called infertility. This problem can be overcome by the artificial insemination process. Sometimes men cannot ejaculate the sperm, thus the process is done in the lab to artificially deduce them and fuse them with female eggs.
