Name Date Test 1: Cell Structure and Function 1. O ur bodies are made of , which are made up of many different parts and are the basic units of life. 1. a. cells b. organelles c. molecules d. proteins 2. A nimal and plants cells contain specialized parts called with a special function. , each 2. a. cells b. organelles c. spores d. cavities 3. 3. What is the relationship between our cells and our bodies? a. Our bodies are made up of cells, and cells keep our bodies alive. b. Our bodies are made up of cells, but cells do not keep our bodies alive. c. Cells keep our bodies alive, but our bodies are not made up of cells. d. Our bodies are not made up of cells, and cells do not keep our bodies alive. © 2014 Amplify Education, Inc. 1 4. W hich sequence correctly shows the levels of increasing organization in the human body? (smallest on the left, largest on the right) 4. a. organelle › molecule › cell › organs › organism b. molecule › organelle › cell › organs › organism c. cell › organelle › molecule › organs › organism d. organelle › molecule › cell › organism › organs 5. If an organism is starving, its cells don’t have enough of which molecule? 5. a. Oxygen (O²) b. Carbon dioxide (CO²) c. Glucose d. Starving will not affect the cells 6. If an organism is choking, its cells don’t have enough of which molecule? 6. a. Oxygen (O²) b. Carbon dioxide (CO²) c. Glucose d. Choking will not affect the cells © 2014 Amplify Education, Inc. 2 7. What happens to the cell if the mitochondria stop working? 7. a. Organelles depend on each other to function normally so the whole cell might stop working. b. Organelles do not depend on each other to function normally so just the mitochondria will stop working and the cell will continue to work normally. c. The cell will get ATP from nearby cells to keep working normally. d. The nucleus will instruct other organelles to work more to make up for the loss of mitochondria. © 2014 Amplify Education, Inc. 3 8. Identify the structure labeled A. 8. a. Nucleus b.

Ribosome © 2014 Amplify Education, Inc. 4 10.Identify the structure labeled C. 10. a. Nucleus b. Cell membrane c. Mitochondrion d. Ribosome 11. 11. Identify the structure labeled D. a. Nucleus b. Cell membrane c. Mitochondrion d. Ribosome 12.In a cell, the nucleus . 12. a. produces energy (ATP) for other parts of the cell to use b. builds proteins, the tools of the cell c. controls which substances can go in to and out of the cell d. sends out instructions (mRNA) that control the activities of other parts of the cell 13.In a cell, the ribosomes 13. . a. produce energy (ATP) for other parts of the cell to use b. build proteins, the tools of the cell c. control which substances can go in and out of the cell d. send out instructions (mRNA) that control the activities of other parts of the cell © 2014 Amplify Education, Inc. 5 14.In a cell, the mitochondrion 14. . a. produces energy (ATP) for other parts of the cell to use. b. builds proteins, the tools of the cell. c. controls which substances can go in and out of the cell. d. sends out instructions (mRNA) that control the activities of other parts of the cell. 15.In a cell, the cell membrane 15. . a. produces energy (ATP) for other parts of the cell to use. b. builds proteins, the tools of the cell. c. controls which substances can go in and out of the cell. d. sends out instructions (mRNA) that control the activities of other parts of the cell. 16.Which of the following is the best explanation for how the cell gets 16. energy (ATP) for itself? a. The nucleus makes ATP (energy) energy for the whole cell. b. The ribosomes make ATP (energy) from the instructions it receives from the nucleus. c. The mitochondria use glucose to make ATP (energy). d. ATP (energy) comes from outside the cell and enters in to the cell by crossing the cell membrane. © 2014 Amplify Education, Inc. 6 17. Which of the following is the best explanation for the role that oxygen 17. plays in the cell? a. Oxygen enters the cell by crossing the cell membrane and then gets used by the mitochondria to make ATP molecules. b. Mitochondria release oxygen into the cell when they make ATP. c. Oxygen controls the amount of glucose that can enter the cell. d. Oxygen combines with carbon dioxide to make glucose. 18. 18.Which of the following is the best explanation for how the cell builds proteins? a. The mitochondria assemble proteins from instructions they receive from the nucleus. b. The ribosomes assemble proteins from instructions they receive from the nucleus. c. The nucleus contains the instructions and so proteins get built inside the nucleus. d. Proteins are made outside the cell and the cell gets proteins when they cross the cell membrane and come into the cell. 19.Which of the following is the best explanation for how the cell controls 19. what enters the cell and what leaves the cell? a. The nucleus decides what comes into and leaves the cell. b. Ribosomes let molecules into and out of the cell. c. Mitochondria allow molecules into and out of the cell. d. The cell membrane allows some molecules to enter the cell and some molecule to leave the cell. © 2014 Amplify Education, Inc. 7 20.Which statement best explains how the nucleus relates to the 20. ribosomes? a. The nucleus stores instructions in the form of ribosomes. b. Ribosomes make proteins using instructions they received from the nucleus. c. The nucleus sends proteins to the ribosome. d. The nucleus and ribosomes don’t relate to each other. 21.Which statement best explains how the cell membrane relates to the 21. mitochondria? a. The cell membrane makes proteins that help the mitochondria function. b. The cell membrane allows mitochondria to enter the cell. c. Mitochondria use glucose that the cell membrane allowed to enter the cell. d. The cell membrane and mitochondria don’t relate to each other. 22.Insulin is a type of . 22. a. cell b. organelle c. food d. protein © 2014 Amplify Education, Inc. 8 23.In humans, insulin helps the cells 23. . a. use oxygen b. remove carbon dioxide c. attack viruses d. use glucose 24. 24.In humans, insulin helps the: a. nucleus produce mRNA. b. mitochondria use glucose. c. cell membrane let glucose into the cell. d. ribosomes make proteins. 25.Without insulin, the amount of glucose inside a cell will . 25. a. increase b. decrease c. change randomly d. stay the same © 2014 Amplify Education, Inc. 9
