Concept:Spermatogenesis is the process of sperm formation from spermatogonia in the seminiferous tubules.
Key Fact:Spermatogonia are diploid stem cells that divide mitotically to give primary spermatocytes, which then undergo meiosis.
Explanation:Statement A is incorrect because spermatogonia undergo mitotic division, not meiotic division.
Statement B is incorrect because primary spermatocytes undergo the first meiotic division (
Meiosis I) to produce secondary spermatocytes, not a mitotic division.
Statement C is correct: secondary spermatocytes undergo the second meiotic division (
Meiosis II) to form haploid spermatids.
Statement D is incorrect because spermatids do not divide by mitosis; they differentiate into spermatozoa.
Statement E is correct: spermatids transform into spermatozoa through a process called spermiogenesis.
Answer:The correct statements are C and E only, which corresponds to option B.
