Biology: REVIEW SHEET MITOSIS Name Key! 1. Review the cell cycle worksheet and be able to label the chart. 2. What is the purpose of mitosis? Replace | Create New daughter cells that are icdentical to the parent cell. (2 diploid somatic cells) 3. State two reasons why humans need mitosis. Information crisis and Surface Area: Volure 4. What is the difference between autosomes and sex chromosomes? What is a karyotype? is a karyotype Autosomes-Chromosome pairs 1-22 (code for body) A picture Sex Chromosomes pair 23 (male or Female) of Ones 5. Draw cytokinesis in an animal and plant cell. Label cleavage furrow and cell plate. Chiromosomes Cleavage furrow Coire Animal Cell Plant Cell 6. Define diploid and haploid. What is our diploid number? What is our haploid munaber? diploid-Complete # of chromosomes (Somatic cells) 23 haploia-1/2 of # of chromosomes (gameres Igerm cells) 7. Draw sister chromatids connected by a centromere. Are these identicaf or similar? Duplicated Chromosome Centromere Identical Sister Chromatids 8. In what phase are the sister chromatids pulled to opposite poles? Ancuphase 9. In what phase is the nucleolus and nuclear membrane visible in one cell? Interprase 10. In what phase are the chromosomes lined up in the middle? Metaphuse 11. In what phase does the nuclear membrane ands nucleolus disappear? Prophase 12. In what phase are the chromosomes visible for the first time? Prophwe Interprice, End of telophuse Cytokinesis (Chromatin) 13. In what phase does the nuclear membrane and nucleolus reappear in two cells? Cophase 14. What structure pulls the sister chromatids apart? Spindle Fibers from Centriones 15. In what stage do centrioles move to opposite poles? Proprase GI 16. In what stage do the centrioles duplicate? Interprese (all crycancies cumplicate) Thats when 17. Is interphase considered a part of mitosis? NO- Mitosis is the division of the nucleus. Biology: REVIEW SHEET MITOSIS THE CELL CYCLE WORKSHEET Name: Key! Part 1-Matching: match the term to the description-Some terms will be used more than once. A. B. C. Metaphase D. Telophase E. F. Anaphase Prophase Interphase Cytokinesis F Anaphase A A Proprase D. Telophase B E cytokinesis interphase C Metuphuse A Prophase 1. The sister chromatids are moving apart. 2. The nucleolus begins to fade from view. 3. A new nuclear membrane is forming around the chromosomes. 4. The cytoplasm of the cell is being divided. 5. The chromosomes are not visible. 6. The chromosomes are located at the equator of the cell. 7. The nuclear membrane begins to fade from view. D+E Begins in Teloppuses . The division (cleavage) furrow appears. F Anaphase C Melaphise A Propnase E cytokinesis B Interphase Meuprase 9. The chromosomes are moving towards the poles of the cell, 10. Chromatids line up along the equator, 11. The spindle is formed. 12. The cell plate forms. 13. Chromosomes are replicated. Sphase of Interphase. DIE Begins in Texopnabe 14. The chromosomes unwind and return to chromatin, 15. The stage where chromosomes organize in the middle. 9 5 PHASES OF THE CELL CYCLE & MITOSIS 11 12 15 16 Identify the cells (by number) which are in the following stages of mitosis fecaphase 4,5,6,8,10, 13, 15, 16, 18 2,14 79 3,12
