Unlike animal cells, plant cells have ____________________ to capture energy from the sun. (nuclei or chloroplasts) 23. DNA, the genetic material of a eukaryotic cell, is located in the cell's ____________________. (nucleus or ribosome) 24. Cells that have no membrane-covered organelles are ____________________. (prokaryotic or eukaryotic) 25. A part of the Golgi complex can pinch off and form a ____________________, which contains digesting enzymes. (lysosome or ribosome) Short Answer: Please answer questions #26-30 on the lined looseleaf paper provided to you. Please answer questions with complete sentences. Thank you. 26. How do the cells of unicellular organisms differ from the cells of multicellular organisms? 27. If a unicellular organism has a cell wall, ribosomes, and circular DNA, is it eukaryotic or prokaryotic? 28. Which of the following would NOT be found in an animal cell: mitochondria, cell wall, chloroplast, ribosome, endoplasmic reticulum, Golgi complex, large vacuole, DNA, chlorophyll? 29.

C 6. D 7. B 8. D 9. B 10. D 11. D 12. A 13. B 14. B 15. C 16. A 17. B 18. D 19. D COMPLETION 20. eukaryotic 21. mitochondria 22. chloroplasts 23. nucleus 24. prokaryotic 25. lysosome SHORT ANSWER 26. The cells of unicellular organisms can survive on their own, but the cells of multicellular organisms must remain a part of the organism's body to survive. 27. Cells with circular DNA are prokaryotic. 28. cell wall, chloroplast, large vacuole, chlorophyll 29. Sample answer: All organisms are composed of one or more cells; the cell is the basic unit of life in all living things; all cells come from existing cells. 30. Support: Plants do not have a skeleton that allows them to stand upright. Cell walls help to support the plant. Protection: When a plant cell loses or gains too much water, the cell wall helps protect the cell membrane from bursting or tearing. |
