DATE: NAME: CHAPTER 5 CLASS: Cell Growth and Division BLM 2-14 Goal • Review your understanding of the phases of the cell cycle. What to Do Write the name of the stage of the cell cycle that corresponds to each event described below. 1. Centromeres divide. ________________ Anaphase 2. Centrioles move to opposite ends of the cell. ________________ prophase - twoofthemtcentrosome 3. Nuclear membranes form around each mass of chromosomes. ________________ Telophase 4. Chromosome strands separate and move toward opposite ends of the cell. ______________ Anaphase 5. A copy of each chromosome is made. ________________ lwterphase 6. Cell membrane pinches together and the cytoplasm of the cell divides. _________________ Cytokines 7. The nuclear membrane disappears. ________________ Prophase 8. Daughter cells form. ___________________ Cytokines 9. Double-stranded chromosomes line up in the centre of the cell. ________________ Metaphase 10. It makes up most of a cell’s life. _________________ lnterphase Short Answer two cells 11. In mitosis, how many cells form from the original cell? _________________ Copyright © 2007, McGraw-Hill Ryerson Limited, a subsidiary of the McGraw-Hill Companies. All rights reserved.
