Chapter 8 HW Cellular Reproduction Due Wed. 12/18/08 1. Outline- Chapter 6- not typed 2. Vocabulary- on a separate sheet of paper number terms and write definitions. When there is 2 words (vs.) be sure to distinguish differences between them. Indent on the line below and write an example or sentence or draw a picture. 1. binary fission 2. chromosomes 3. asexual reproduction 4. sexual reproduction 5. sister chromatid 6. chromatin 7. centromere 8. cytokinesis 9. centrosomes 10. growth factor 11. metastasis 12. homologous chromosomes 13. autosomes vs. sex chromosomes 14. haploid vs. diploid 15. genetic recombination 16. zygote 17. chiasmata vs. tetrad 18 crossing over 19. non-disjunction 20. karyotype 3. Review questions- number each one and answer on a separate sheet of paper, you do not need to rewrite the questions. 1. Identify the roles of cell division in living organisms 2. Distinguish between events in interphase, mitosis, and cytokinesis- when and why does the eukaryotic chromosomes duplicate? 3. Describe the movements of chromosomes in prophase, metaphase, anaphase, and telophase of mitosis 4. Define the following terms: checkpoint, chiasma, chromosome, chromatid, centromere, crossing over, homologous chromosome pair, nondisjunction, and spindle 5. Describe what happens in Down’s syndrome, Kleinfelters, Turner Syndromes 6. Compare and contrast the processes of mitosis and meiosis 7. Distinguish between terms in the following groups: haploid—diploid; sister chromatids—nonsister chromatids;deletion—duplication—inversion— translocation. 8. Identify factors that control cell division and describe how cancer cells escape these controls include 3 critical checkpoints 9. Describe how genetic variability is generated through meiosis and fertilization. 10. Explain how altered chromosomes strucure can cause birth defects and cancer.
