GAMETOGENESISa. Oogenesis

stages of meiosis in the femaleovarian maturation, hormones and cyclesovulation

b. Spermatogenesisstages of meiosis in the maledifferentiation (spermiogenesis)

TERMS TO REMEMBER:

Gamete: egg or spermGametogenesis: production of eggs or spermOogenesis: production of eggsSpermatogenesis: production of spermSpermiogenesis: is the maturation process into spermFollicle: where eggs mature in the ovaryOvulation: release of egg from folliclePolar body: nonfunctional product of meiotic

divisions in oogenesisZygote: Fertilized egg

Page 3: Gemetogenesis

Oogonia: mitotically dividing cells in the ovary, will becomeOocytes

Primary oocyte: decision has been made to undergo meiosis, cell has grown. Cells are arrested at this stageuntil puberty.

Secondary oocyte: has completed first meiotic divisionthe division was unequal in terms of cytoplasm

Ovum: Ovulated egg, ready to be fertilized. If fertilized,the second meiotic division will occur, another polar bodywill be given off.
