Question 21

what happens when ovulation occurs?

Answer 21

the follicle ruptures leaving behind a CORPUS
LUTEUM, which secretes PROGESTERONE, allowing the endometrium to thicken.

Question 22

difference between spermatogenesis and oogenesis

Answer 22

1. spermatogenesis occurs in the seminiferous tubules in the testes while oogenesis occurs in the ovary
2. spermatogenesis forms 4 spermatozoa while oogenesis forms 1 secondary oocyte, 2-3 smaller polar bodies
3. spermatogenesis starts at puberty and continues into old age. uninterrupted until death
   oogenesis starts when the female is a foetus then stop. resumes at puberty and an egg is released month.ly
   terminates at menopause
4. in spermatogenesis 200 sperms are released daily. fully matured
   while in oogenesis one secondary oocyte is released every menstrual cycle

Question 23

function of the spermatozoa

Answer 23

The role of spermatozoa is to transport the male genetic
material to the female gamete.

Question 24

difference between spermatozoa and secondary oocyte

Answer 24

spermatozoa is 3um while oocyte is 100um
spermatozoa is motile while oocyte is non motile
spermatozoa is haploid- x and y chromosome while oocyte is haploid x chromosome

spermatozoa has limited food while oocyte has considerably more
