Name_________________________ 7.1, 7.2 Cell Structure and Function Test Review 1. Who used a compound microscope to see chambers within cork and named them “cells”? (p. 190) ___________________________________________________________________________ 2. What is the cell theory? (p. 191)_________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ 3. Which type of microscope can produce three-dimensional images of a cell’s surface? (p. 192) ___________________________________________________________________________ 4. Electron microscopes can reveal details (p. 192) only in specimens that are still alive. about the different colors of cell structures. 1000 times smaller than those visible in light microscopes. 5. Looking at a cell under a microscope, you note that it is a prokaryote. How do you know? (p. 194) ___________________________________________________________________________ 6. Which of the following enclose their DNA in a nucleus? (p. 194) prokaryotes eukaryotes bacteria 7. Which of the following organisms are prokaryotes? (p. 194) plants bacteria animals 8. Which of the following is a function of the nucleus? (p. 197) stores DNA builds protein stores sugars 9. Which of the following is NOT found in the nucleus? (p. 197) mitochondria. Chromatin nucleolus 10. Which organelle breaks down organelles that are no longer useful? (p. 198) ___________________________________________________________________________ 11. Which of the following is a function of the cytoskeleton? (p. 199) helps a cell keep its shape surrounds the cell contains DNA 12. Which structure makes proteins using coded instructions that come from the nucleus? (p. 200) ___________________________________________________________________________ 13. Which sequence correctly traces the path of a protein in the cell? (pp. 200-201) ___________________________________________________________________________ 14. Which organelle would you expect to find in plant cells but not animal cells? (p. 202) ___________________________________________________________________________ 15. Which organelle converts the chemical energy stored in food into useable energy? (p. 202) ___________________________________________________________________________ 16. Which of the following is a function of the cell membrane? (p. 204) breaks down lipids, carbohydrates, and proteins from foods stores water, salt, proteins, and carbohydrates regulates the movement of materials into and out of the cell 17. Which of the following structures serves as the cell’s boundary from its environment? (p. 204) mitochondrion chloroplast cell membrane 18. Which structure in the cell shown in Figure 7–1 above stores materials, such as water, salts, proteins, and carbohydrates? (p. 205-206) ___________________________________________________________________________ 19. All cells come from existing . (p. 191) 20. Summarize three statements from the cell theory. (p. 191) __________________________________________________________________________ __________________________________________________________________________ __________________________________________________________________________ 21. The cell’s genetic information is found in the cell’s nucleus as threadlike ___________________, which are made of chromatin and protein. (p. 197) 22. In plants, energy.(p. 202) _ capture energy from sunlight and convert it into chemical 23. Unlike smooth endoplasmic reticulum, rough endoplasmic reticulum has__________________________ attached to it. (p. 205) 24. How do prokaryotes and eukaryotes differ? (p. 194) _________________________________________________________________________________ _________________________________________________________________________________ Figure 7–3 25. Identify each of the cell structures indicated in Figure 7–3. Use these terms: nucleus, mitochondrion, ribosome, cell membrane, smooth endoplasmic reticulum, rough endoplasmic reticulum, nucleolus, Golgi apparatus, cytoplasm. (p. 206) _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ Use the diagram below to answer the following questions on the lines provided. Figure 7–4 26. Interpret Visuals Which drawing in Figure 7–4, I or II, contains structures that carry out photosynthesis? What is this structure labeled in the diagram? (p. 206) _________________________________________________________________________________ _________________________________________________________________________________ 27.
