Ribosome  \n   B. Nucleus  \n   C. Mitochondrion  \n   D. Cell membrane  \n\n2. **Which organelle produces the energy currency (ATP) for the cell?**  \n   A. Chloroplast  \n   B. Nucleus  \n   C. Mitochondrion  \n   D. Vacuole  \n\n3. **Which organelle is found only in plant cells and is responsible for photosynthesis?**  \n   A. Ribosome  \n   B. Mitochondrion  \n   C. Chloroplast  \n   D. Cell wall  \n\n4. **Which structure is present in both plant and animal cells and controls what enters and leaves the cell?**  \n   A. Cell wall  \n   B. Nucleus  \n   C. Cell membrane  \n   D. Vacuole  \n\n5. **Which structure is found only in plant cells and provides rigidity and shape?**  \n   A. Cell membrane  \n   B. Cell wall  \n   C. Mitochondrion  \n   D. Chloroplast  \n\n6. **Which organelle stores water, nutrients, and waste products, and is usually very large in plant cells?**  \n   A. Nucleus  \n   B. Vacuole  \n   C. Ribosome  \n   D. Chloroplast  \n\n7. **According to the cell theory, which statement is NOT true?**  \n   A. All living things are made of cells.  \n   B. The cell is the basic unit of life.  \n   C. All cells arise from pre\u2011existing cells.  \n   D. Cells can spontaneously arise from non\u2011living matter.  \n\n---\n\n### Short\u2011Answer (Write a brief response)\n\n8. **Explain the main structural difference between a plant cell and an animal cell.**  \n\n9. **Describe the function of the cell membrane.**  \n\n10. **Why is the cell theory important for biology?**  \n\n---\n\n## Answer Key\n\n| # | Correct Answer | Sample Full\u2011Credit Short\u2011Answer |\n|---|----------------|---------------------------------|\n| 1 | **B** | The nucleus contains the cell\u2019s DNA and directs cell activities. |\n| 2 | **C** | Mitochondria generate ATP through cellular respiration. |\n| 3 | **C** | Chloroplasts contain chlorophyll and carry out photosynthesis. |\n| 4 | **C** | The cell membrane is a phospholipid bilayer that regulates traffic in and out of the cell. |\n| 5 | **B** | The cell wall is a rigid, cellulose layer that gives plant cells shape and protection. |\n| 6 | **B** | The vacuole stores water, ions, and waste; it also helps maintain turgor pressure in plant cells. |\n| 7 | **D** | The cell theory states that cells do not arise spontaneously; they come from pre\u2011existing cells. |\n| 8 | **Answer example:** Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells lack a cell wall and chloroplasts and usually have many small vacuoles. |\n| 9 | **Answer example:** The cell membrane controls the movement of substances into and out of the cell, protecting the cell\u2019s internal environment. |\n|10 | **Answer example:** The cell theory explains that all living organisms are made of cells, that the cell is the basic unit of life, and that new cells come from existing ones\u2014principles that guide all biological research and understanding. |\n\nFeel free to print or copy this quiz into your lesson plan.
