Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

1. metaphase I meiosis ___________________ homologous chromosome line up in the
center of the cell
2 ________________________________________ The individual chromosomes move apart.
3.________________________________________ spindle fibers pull homologous pairs to
ends of the cell
4. _______________________________________ 4 haploid (N) daughter cells form
5. _______________________________________ cells undergo a round of
6. _______________________________________ The chromosomes line up across the
middle of the cell.
7. _______________________________________ Chromosomes become visible.
8.________________________________________ sister chromatids separate from each
other
9. _______________________________________ 2 haploid (N) daughter cells form
10. ______________________________________ Sister chromatids separate into individual
chromosomes.
11. ______________________________________ Nuclear envelope re-forms.
12._______________________________________ spindle fibers attach to the homologous
chromosome pairs
13. ______________________________________ individual chromatids move to each end
of the cell
14. ______________________________________ The nucleolus disappears and the nuclear
envelope beaks down.
15. ______________________________________ Each chromosome is connected to a
spindle fiber.
16._______________________________________ crossing-over (if any) occurs
