1. Explain the importance of the G1 and S stage in Interphase. 2. A cell was noted to have a cleavage furrow. Would the cell be a plant or animal cell? Justify your answer. 3. An onion cell is noted to have 8 chromosomes. Would this cell with 8 chromosomes have been produced by mitosis? Why or why not? 4. How many daughter cells are produced at the end of mitosis and at the end of meiosis? Why is there a difference in the number of daughter cells produced? 5. In the cell cycle (A), chromosomes can present as a single chromosome or duplicated chromosome (see B below). A B Gap 1 phase S phase mitosis Gap 2 phase Stage Single chromosome Gap 1 S phase Gap 2 Prophase (mitosis) Centromere If you observe cells during the different stages of the cell cycle which type of chromosomes will you find? Single or double? Use the table below to provide your answer. Duplicated Duplicated chromosome & Single Centromere Chromatid Chromatid
