Which of the following pairs of terms is NOT related? a. nucleus --- DNA b. chloroplasts --- chlorophyll c. flagella --- chromatin d. cell wall --- cellulose 3. Which of the following structures is NOT found in both plant and animal cells? a. chloroplast b. ribosomes c. cytoskeleton d. mitochondria 4. Ribosomes _____________________. a. do not have a cell wall b. are not surrounded by a membrane c. do not contain cytoplasm d. all of the above 5. A bacterium is classified as a prokaryote because it ______________________. 6. The ___________________________ maintains a chemical balance within a cell by regulating the materials that enter and leave the cell. 7. Plants are able to grow tall because their cells have rigid _______________________ that contain a strong network of (are made of) __________________________. 8. Although prokaryotes lack ______________________, they still contain DNA. 9. Microtubules and microfilaments, which make up the cell cytoskeleton, are composed of ____________________. 10. A plant cell has a green color due to the presence of ________________________, a pigment that is embedded in the _________________________ membranes of the _________________________. 11. Cilia and flagella are an arrangement of _________________________ and allow the cell to _________________. 12. The structures that store water, other liquids, or food particles are ________________________. 13. Chromoplasts contain the ___________________ responsible for orange and yellow color in fruits, flowers and autumn leaves. 14. According to the cell theory, all cells come from _________________________. 15. _______________________ are structures that perform specialized functions within the cell. 16. Why do cells not grow indefinitely? 17. a. What is the advantage of highly folded membranes in a cell? b. Name an organelle that uses this strategy. 18. What organelleS would be especially numerous in a cell that produces large amounts of a protein product? 19. Why are digestive enzymes in a cell enclosed in a membrane-bound organelle? 20. Why might a cell need a cell wall in addition to a plasma membrane? 21. How do your cells and the cells of other organisms that are not green plants obtain food energy from the chloroplasts of green plants? 22. Sketch a plant cell. Include the following organelles and label them: cell wall, cell membrane, large central vacuole, nucleus, nucleolus, ER, chloroplast, mitochondria, Golgi body
