Chapter 7 Cells Review Sheet Matching: On the lines provided, match the term with its definition. _______1. cell _______2. cell membrane _______3. cell wall _______4. nucleus _______5. cytoplasm _______6. prokaryote _______7. eukaryote _______8. organelle _______9. chromatin _______10. phagocystosis 11. 12. 13. 14. a. organism whose cells contain a nucleus b. granular material visible within the nucleus c. the basic unit of life d. specialized structures within a cell that perform important cell functions e. organism whose cells do not contain a nucleus f. strong layer around the cell membrane that protects the cell g. process by which extensions of the cytoplasm engulf large particles h. large structure that contain the cell’s genetic information i. Thin, double-layered sheet around the cell j. portion of the cell outside of the nucleus The small dense region in the nucleus where the assembly of ribosomes begins is called the a. Nucleolus c. Nuclear envelope b. Chloroplast d. Vacuole Which organelles can use energy from sunlight to create energy-rich food molecules? a. Lysosomes c. Golgi apparati b. Vacuoles d. Chloropasts What is the process by which material is taken into the cell by infoldings of the cell membranes? a. Diffusion c. endocytosis b. Osmosis d. exocytosis The fourth, and highest, level of organization in a multicellular organism is a. cell specialization c. a tissue b. an organ system d. an organ 15. Enkaryotic cells also have dozens of specialized structures called . 16. What structures make plant and animal cells different? ______________________________________________________ ______________________________________________________ ______________________________________________________ 17. Using Analogies in some ways, a cell is analogous to a factory. Create an analogy describing the job of a lysosome within a cellular “factory.” ______________________________________________________ ______________________________________________________ ______________________________________________________ 18. What are two functions of the cell membrane? ______________________________________________________ ______________________________________________________ 19. What happens to a high concentration of water molecules on one side of a cell membrane during the process of diffusion? ______________________________________________________ ______________________________________________________ On the lines provided, label each diagram as showing an isotonic, a hypotonic, or a hypertonic solution and describe how the concentration of water molecules will affect the shape of the cell. Water molecule Membrane 20. _______________________________________________ _______________________________________________ _______________________________________________ Solution Cell Sugar Molecules Membrane 21. _______________________________________________ __ _______________________________________________ Cell Solution Water molecules Membrane Water 22. _______________________________________________ _______________________________________________ _______________________________________________ Cell Solution Sugar Molecules 23. Why do multicellular organisms contain specialized cells? _____________________________________________________________ _____________________________________________________________ 24. Give two examples of specialized cells and explain the cell’s unique role in the human body? _____________________________________________________________ _____________________________________________________________ On the line provided, order the following terms in order from smallest to largest level of cellular organization. 25. _______________ tissues 26. _______________ organ systems 27. _______________ organs 28. _______________ individual cells 29. How are tissues and organs different? _______________________________________________________________
