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:
Meiosis stage descriptions
7. homologous pairs line up as tetrads along the middle of the cell
8. one of each homologous pair reaches the ends of the cell, the cell begins pinching in, and two new nuclear membranes form
9. DNA condenses in two haploid cells, the nuclear membranes disintegrate
10. sister chromatids split apart and daughter chromosomes move towards the ends of two cells
11.
12. four cells with half of the genetic material of a body cell result, all are different from each other
Match the picture or the image with the name of the stage it represents. Use each stage just once for either an image or description.
