GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.

Detailed explanation-3: -Each primary spermatocyte undergoes the first meiotic division to yield a pair of secondary spermatocytes, which complete the second division of meiosis. The haploid cells thus formed are called spermatids, and they are still connected to one another through their cytoplasmic bridges.

Detailed explanation-4: -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.

Detailed explanation-5: -No, primary spermatocytes do not undergo mitosis. They undergo meiosis to form four haploid spermatids.
