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.
