Chapter 12: Mitosis & The Reproduction of Cells Name AP Biology Date Mr. Mennecke 1. Which process is not associated with the reproduction of bacteria? a. replication of DNA b. binary fission c. mitosis d. synthesis of new cell wall material 2. Through a microscope, you can see a cell plate beginning to develop across the middle of the cell and 2 new nuclei reforming at opposite poles of the cell. This cell is most likely a (an) a. animal cell in the process of cytokinesis b. plant cell in the process of cytokinesis c. animal cell in the S phase of the cell cycle d. bacterial cell dividing 3. In a typical cell cycle, cytokinesis generally overlaps in time with which stage? a. S phase c. anaphase b. telophase d. metaphase 4. A particular cell has half as much DNA as some of the other cells in mitotically active tissue. The cell in question is most likely in a. G1 c. metaphase b. G2 d. prophase 5. One difference between a cancer cell and a normal cell is that a. the cancer cell is unable to synthesize DNA b. the cell cycle of the cancer cell is arrested at the S phase c. cancer cells continue to divide even when they are tightly packed d. cancer cells cannot function properly because they suffer from density-dependent inhibition 6. The decline of MPF at the end of mitosis is caused by a. apoptosis b. the enzymatic degradation of the cyclin c. synthesis of DNA d. an increase in the cell’s volume-to-genome ratio 7. Which of the following is not a function of mitosis in humans? a. growth & wound repair b. embryonic development c. production of gametes (sex cells) d. replacement of blood cells 8. In function, the plant cell structure that is analogous to an animal cell’s cleavage furrow is the a. chromosome b. cell plate c. nucleus d. centrosome Chapter 12: Mitosis & The Reproduction of Cells 9. In some organisms, mitosis occurs without cytokinesis occurring. This results in a. cells with more than one nucleus b. cells that are unusually small c. cells lacking nuclei d. destruction of chromosomes 10. Explain the acronym “RALPH IPMAT” in relation to the process of mitosis. 11. A somatic cell with two of each type of chromosome characteristic of the species has a(n) __________ chromosome number. a. diploid c. abnormal b. haploid d. a & c 12. A duplicated chromosome has _________ chromatid(s). a. one b. two c. three d. four 13. In a chromosome, a __________ is a centrally located constricted region with attachment sites for microtubules. a. chromatid b. centromere c. cell plate d. cleavage furrow 14. Interphase is the part of the cell cycle when _____________. a. b. c. d. a cell ceases to function a germ cell forms its spindle apparatus a cell grows and duplicates its DNA mitosis proceeds 15. After mitosis, the chromosome number of a daughter cell is ____________ the parent cell. a. the same as b. one-half c. rearrange compared to d. double compared to 16. Mitosis and cytoplasmic division function in _____________. a. asexual reproduction of single-celled eukaryotes b. growth, tissue repair, and sometimes asexual reproduction c. gamete (sex cell) formation in prokaryotes d. both a & b Matching: 17. metaphase a. sister chromatids move apart 18. prophase b. chromosomes start to condense 19. telophase c. chromosomes relax & daughter nuclei form 20. anaphase d. all duplicated chromosomes are aligned at the spindle equator 21. interphase e. chromosomes undergo duplication, nucleus present Chapter 12: Mitosis & The Reproduction of Cells 22. Match each picture below with the corresponding phase from the above section. a. b. d. c. e.
