Circle the letter of the best answer. Part B has 3 short-answer questions (4 points each). Answer in complete sentences. Total: 26 points.\nPart A: Multiple Choice\n1. Which organelle is known as the \"control center\" of the cell because it holds the cell's DNA?\nA. Vacuole\nB. Nucleus\nC. Cell membrane\nD. Mitochondria\n2. Which organelle releases energy from food so the cell can use it?\nA. Mitochondria\nB. Chloroplast\nC. Cell wall\nD. Nucleus\n3. Chloroplasts use sunlight to make food for the cell. In which type of cell would you find chloroplasts?\nA. Animal cells only\nB. Both plant and animal cells\nC. Plant cells only\nD. Neither plant nor animal cells\n4. Which structure controls what enters and leaves a cell?\nA. Cell membrane\nB. Nucleus\nC. Chloroplast\nD. Vacuole\n5. A student looks at a cell under a microscope. It has a rigid outer layer, a large central vacuole, and green chloroplasts. What kind of cell is it most likely?\nA. A human skin cell\nB. A plant leaf cell\nC. A dog muscle cell\nD. A human blood cell\n6. What is the main job of a vacuole?\nA. To make food using sunlight\nB. To store water, food, and waste\nC. To hold the cell's DNA\nD. To give the cell energy\n7. Which statement is NOT part of the cell theory?\nA. All living things are made of one or more cells.\nB. The cell is the basic unit of structure and function in living things.\nC. All cells come from other cells that already exist.\nD. All cells have a cell wall and chloroplasts.\nPart B: Short Answer\n8. Name two structures found in plant cells but not in animal cells. For each one, explain its job.\n9. Both plant and animal cells have mitochondria. Explain why a plant cell needs mitochondria even though it already has chloroplasts.\n10. State the three parts of the cell theory. Then choose one part and give an example that supports it.\nAnswer Key (Teacher Copy)\nPart A (2 points each)\n#\nAnswer\nWhy\n1\nB\nThe nucleus holds DNA and directs the cell's activities.\n2\nA\nMitochondria break down food (sugar) to release energy.\n3\nC\nOnly plant cells (and some algae) have chloroplasts for photosynthesis.\n4\nA\nThe cell membrane is selectively permeable and controls traffic in and out.\n5\nB\nA cell wall, large central vacuole, and chloroplasts point to a plant cell.\n6\nB\nVacuoles store water, food, and waste; in plants a full vacuole also helps the cell keep its shape.\n7\nD\nAnimal cells have no cell wall or chloroplasts, so this is not part of the cell theory.\nPart B (4 points each)\n8. Sample full-credit answer: Plant cells have a cell wall and chloroplasts, but animal cells do not. The cell wall is a stiff outer layer that supports and protects the plant cell and helps it keep its shape. Chloroplasts capture energy from sunlight to make food (sugar) through photosynthesis.\n• 1 point for each correct structure named (2 total); 1 point for each correct job (2 total).\n• Also accept a large central vacuole as one structure if the student explains it stores water and helps the plant stay firm. Animal cells may have small vacuoles, so the key idea is the large central one.\n9. Sample full-credit answer: Chloroplasts make food (sugar) using sunlight, but they do not release the energy stored in that food. Mitochondria break down the sugar to release energy the cell can use to grow, repair, and do its work. A plant needs both: chloroplasts to make the food and mitochondria to get energy out of it. Mitochondria also keep working at night when there is no sunlight.\n• 2 points: chloroplasts make food / store energy in sugar.\n• 2 points: mitochondria release energy from that food for the cell to use.\n• Watch for the misconception that \"plants get energy from the sun, so they don't need mitochondria.\"\n10. Sample full-credit answer: The three parts of the cell theory are: (1) all living things are made of one or more cells, (2) the cell is the basic unit of structure and function in living things, and (3) all cells come from cells that already exist. For example, when I scrape a cut on my knee, new skin cells form by dividing from the skin cells I already have. This supports the idea that all cells come from other cells.\n• 1 point for each correct part of the cell theory (3 total).\n• 1 point for a reasonable example tied to one part. Other good examples: a microscope view of an onion skin or cheek cells showing living things are made of cells; a single-celled organism like an amoeba or bacterium as a complete living thing made of one cell.\nTotal: 26 points (Part A 14 + Part B 12)\n", "capture_note": "Claude's chat reply, then the Claude Docs document text as copied (tables copy as one cell per line; document links copy as plain text)"}
