1. Your class has been studying cell division in a number of organisms with different chromosome numbers. Unfortunately, the slides showing the different stages of mitosis and meiosis got mixed up, and some of them got lost. The figures below show the 12 slides that you have managed to find. The organism that you have been studying has a 2n number of 8 with one pair of large metacentric chromosomes, one pair of small metacentric chromosomes, one pair of acrocentric chromosomes and one pair of telocentric chromosomes. a. Do any of the recovered slides below show the stages of cell division indicated in the table in the answer sheet? If so, please write only the slide number in the correct place in the table on your answer sheet. b. Consider slide 6 above. What chromosomal event / phase of cell division is being shown here? c. What is wrong with the picture of this stage of cell division?

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:
