After meiosis, what differentiates into the mature sperm?
Correct answer: B. Spermatid
- A. Primary spermatocyte
- B. Spermatid
- C. Secondary spermatocyte
- D. Spermatogonium
Explanation
After meiosis, the primary spermatocyte differentiates into two secondary spermatocytes. These secondary spermatocytes then undergo a second round of division to form spermatids. Finally, spermatids undergo maturation and differentiation into mature sperm cells, also known as spermatozoa. The process involves morphological changes, including the formation of a tail (flagellum) and reduction of excess cytoplasm to produce a streamlined, functional sperm cell.
