Question 4

Zygote

Answer 4

Question 5

Spermatogenesis

Answer 5

It takes place in the seminiferous tubules. Spermatogonia divide by mitosis; some become spermatocytes, which undergo meiosis. The first meiotic division produces two secondary spermatocytes. The second meiotic division produces two secondary spermatocytes per primary spermatocytes.

Question 6

Acrosome

Answer 6

The cap covering the nucleus that contains enzymes that help the sperm penetrate the egg.

Question 7

Oogenesis

Answer 7

Oogonia differentiate into primary oocytes. A primary oocyte and the granulosa cells surrounding it make up a follicle.
As it grows a layer of theca cells is produced. As the follicle matures, the primary oocyte undergoes the first meiotic division giving rise to a secondary oocyte and a polar body.
During ovulation, the secondary oocyte is ejected from the ovary and enters one of the paired oviducts.
