Question

Read the following statements (a to e) and choose the option with only correct statements.

(a) Primary spermatocytes undergo spermiogenesis to form secondary spermatocytes.

(b) Secondary spermatocytes periodically undergo meiosis to form sperms and seminal plasma.

(c) First meiotic division is completed prior to ovulation.

(d) Primary oocyte is formed after puberty and completes its meiosis to form secondary oocyte.

(e) Oogonia undergo mitosis and differentiation to form primary oocyte.

Answer 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.
Primary spermatocytes periodically undergo meiosis.
Primary oocyte is formed before delivery of female child.
