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:
Step by step

- Abiologist prepares a slide ofstained cells undergoing mitotic prometaphasefor examination undera light microscope. He sees several very dark stained rod – shaped structures in the cells. These “colored bodies” are most likely?for each phase of mitosis make sure you can describe the events that take places as well as the mechanism(I.e from where to do microtubles form? How do they attach? What proteins are involved in chromosomes condensation? Etc)MIosis Method: Observations of onion root tip squash. Scan the microscope under the 10x objective. Look for the region that has large nuclei relative to the size of the cell; among these cells will be found cells displaying stages of mitosis. Switch to the 40X objective to make closer observations. Since prophase and prometaphase are difficult to distinguish, classify all these cells as prophase. Record your observations in the table provided. Examples are shown in the figure below. Interphase Early Prophase Mid Prophase 10 Metaphase Anaphase Telophase Exercises: 1. Find and draw a cell showing each stage of mitosis. Interphase Prophase Metaphase Anaphase Telophase , 2. What is a distinguishing visible feature of each stage of mitosis? Interphase: Prophase: Metaphase: Anaphase: Telophase: Many of the cells of the root meristem are not undergoing mitosis; rather they Based upon the interpretations 3. are in a stage called 21
- mitotic index: Interphase = 80 cells Prophase = 9 cells Metaphase = 5 cells Anaphase = 2 cells Telophase = 4 cells The average duration for the cell cycle in this culture is known to be 20 hours. Use the data above to work out the duration of interphase and metaphase.EXERCISE 5 MITOSIS AND MEIOSIS COMPARISON Work with a group of your classmates to review the cell division processes in Exercises 3 and 4 (or the diagrams of mitosis and meiosis from Figures 2.8 and 2.9). Use the information to compare the two processes of cell division and complete the following chart and questions. For each of the descriptions on the left, place a mark in the appropriate cell division column on the right.

You will also view an onion root tip and calculate the percentage of cells at each of the stages of cell division. Stages of Mitosis Answer the following questions: 1. Which stage does each of the following occur? Chromatin condenses into chromosomes Chromosomes align in center of cell. Longest part of the cell cycle. Nuclear envelope breaks down. Cell is cleaved into two new daughter cells. Daughter chromosomes arrive at the poles. Chromatids are pulled apart 2. Answer the following questions. You can review the steps of mitosis using the following online activity https://www.oppia.org/explore/q4NBr1JG7Qrt: ● AV ● ● How many chromosomes are visible at the beginning of mitosis?

Make sure to draw the alleles for genes A and B on the chromatids in every stage. For mitosis, remember that many events are going on in the cell that are relevant besides just the movement of chromosomes, so please fill in the cell with pertinent structures such as centrioles and spindles.
