As two students, who will be designated Student J and Student K, were studying together, they argued about the differences between Mitosis and Meiosis (both Meiosis I and Meiosis II). Student J maintained that it if they were looking at very good slides under the microscope and concentrated on Metaphase, it would be possible to tell the difference between the cells undergoing Mitosis, the cells undergoing Meiosis I, and the cells undergoing Meiosis II. Student K said it would be impossible to tell which nuclear division was occurring. Assume there are three unlabeled sets of very good slides of the cells of the common pea plant with one set showing Mitosis, one set showing Meiosis I, and one set showing Meiosis II. To repeat, the slides are unlabeled so the students don’t know which process is occurring in which set. However, the students know that the common pea plant has 14 total chromosomes (or 7 pairs of chromosomes). Explain carefully what Student J would be looking for at the Metaphasic plate in each set of slides to be able to be certain what process was occurring in the pea plant. In your answer, be very specific about the number of chromosomes, chromatids, tetrads (or whatever is involved) lining up at the Metaphasic plate. Also be specific about the nature of each of the chromosomes or chromatids (identical to each other or to the parent cell or what). This answer requires three parts: Part A-what is expected for Mitosis, Part B-what is expected for Meiosis I, and Part C-what is expected for Meiosis II.
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:
