Which of the following cells undergoes meiosis to produce four sperm?

  • A. Spermatids
  • B. Spermatogonium
  • C. Primary spermatocyte
  • D. Ovum
Correct Answer: C

Rationale: The correct answer is C: Primary spermatocyte. Primary spermatocytes are diploid cells that undergo meiosis to produce four haploid cells, which develop into sperm. First, primary spermatocytes undergo meiosis I to form two secondary spermatocytes. Then, meiosis II occurs in each secondary spermatocyte to produce a total of four spermatids, which eventually mature into sperm.

Explanation for why other choices are incorrect:
A: Spermatids are already haploid cells formed from the division of secondary spermatocytes, not primary spermatocytes.
B: Spermatogonium are diploid cells that divide by mitosis to produce primary spermatocytes, not directly giving rise to sperm.
D: Ovum is a female gamete that undergoes meiosis to produce one mature egg cell, not sperm.
