Twenty Questions Subject: Cell Cycle Twenty Questions 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1. What is mitosis? A. B. C. D. A cell divides from one parent cell into two identical daughter cells A cell divides from one parent cell into two different daughter cells A cell divides from one parent cell into four different daughter cells A cell divides from one parent cell into four identical daughter cells 2. Which cell cycle stage is the longest? A. B. C. D. Interphase Mitosis Cytokinesis Cell Division 3. Why do cells divide? A. B. C. D. Growing organisms need more cells The volume of the cell gets to large for the surface area of the cell To repair damaged cells All of the above 4. What is the correct order of the phases of mitosis? A. B. C. D. Prophase, Anaphase, Telophase, Metaphase Prophase, Metaphase, Anaphase, Telophase Telophase, Metaphase, Prophase, Anaphase Prophase, Metaphase, Telophase, Anaphase 5. What are the levels of biological organization (increasing order)? A. B. C. D. Cells, Tissues, Organs, Organ Systems, Organisms Tissues, Cells, Organs, Organ Systems, Organisms Organisms, Organ System, Organs, Tissues, Cells Organisms, Organs, Organ System, Tissue, Cells, 6. In what stage do sister chromatids move apart? A. B. C. D. Metaphase Prophase Anaphase Telophase 7. In what stage does the nuclear membrane start to disappear? A. B. C. D. Metaphase Prophase Anaphase Telophase 8. In what stage does the cytoplasm divide? A. B. C. D. Interphase Prophase Metaphase Cytokinesis 9. What are the three main stage of interphase A. B. C. D. G1, G2, S G1, G3, S Interphase, Cell Division, Mitosis Prophase, Metaphase, Anaphase 10. What happens during interphase? A. B. C. D. Normal cell function Cell grows DNA replication All of the above 11. If there are 4 chromosomes in the cell at interphase, how many chromosomes will be present after telophase? A. B. C. D. 4 2 12 8 12. What is cytokinesis? A. B. C. D. Dividing the nucleus Replicating the DNA Split the parent cell into two daughter cells Makes the cell bigger. 13. Which is the chromatids? Type A the answer here. C B 14. Which is the centromere? Type A the answer here. C B 15. Which is the sister chromatids? Type A the answer here. C B 16. What happens in cancer cells? A. B. C. D. The DNA mutates and is passed along to the daughter cells. Division happens rapidly and cancer spreads. The daughter cells do not divide. The parent cell does not divide. One daughter cell is bigger than the other daughter cell. 17. What is homeostasis? A. B. C. D. Regulation of the internal environment of an organism How your body functions Regulation of the external environment of an organism How organisms survive 18. What is one topic that helps to maintain homeostasis? Bonus if you can name the other two A. B. C. D. Maintaining blood sugar Structure and function Cell Division Temperature 19. What do spindle fibers do (orange yarn)? A. B. C. D. Pull apart sister chromatids to opposite ends of the cell Breaks the centromeres of the sister chromatids Condenses chromosomes Breaks the cell into two cells 20. Explain one way homeostasis works. Could talk about how body regulates glucose, sweat, or water Could talk about structure function, division of labor, and interdependence of organ systems. Ex: Body gets to hot= sweat to cool you down; Body gets cold= shiver to keep warm, blood circulates towards the center of body the best
