Question

(a) Draw a sectional view of seminiferous tubule of a human. Label the following cells in the seminiferous tubule: (i) Cells that divide by mitosis to increase their number, (ii) Cells that undergo meiosis I, (iii) Cells that undergo meiosis II, (iv) Cells that help in the process of spermiogenesis.
(b) Mention the role of Leydig cells.

Hint:

- Mitosis cells = Spermatogonia - Meiosis I cells = Primary spermatocytes - Meiosis II cells = Secondary spermatocytes - Spermiogenesis helper cells = Sertoli cells - Leydig cells sit outside the tubules and produce testosterone under LH stimulation.
