Cells and the Cell Theory Test Name:_______________ Class:_________ Date:_______________ 1. All of the following are true regarding cells except? 1) 2) 3) 4) 7. Which instrument was used in the 18th and 19th centuries and helped scientists develop the cell theory? All cells have genetic material All cells have cell walls All cells have plasma membranes All cells can divide to form new cells 2. The diagram below represents levels of organization in living things. 1) 2) 3) 4) electron microscope light microscope microdissecting apparatus ultracentrifuge 8. Which is the correct sequence of historical developments leading to our present knowledge of cells? 1) electron microscope --> cell theory -->compound light microscope 2) compound light microscope --> cell theory -->electron microscope 3) cell theory --> electron microscope --> compound light microscope 4) electron microscope --> compound light microscope -->cell theory 9. Which statement best describes the organelles in a cell? 1) All organelles are involved directly with communication between cells. 2) Organelles must work together and their activities must be coordinated. 3) Organelles function only when there is a disruption in homeostasis. 4) Each organelle must function independently of the others in order to maintain homeostasis. Which term would best represent X? 1) human 3) stomach 2) tissue 4) chloroplast 10.Which cell structures are correctly paired with their functions? 3. Which statement is not a part of the cell theory? 1) 2) 3) 4) 1) The mitochondria produce enzymes, and ribosomes transport them. 2) The ribosomes make proteins, and the nucleus stores genetic information. 3) The cell membrane make enzymes, and cytoplasm transports them. 4) The vacuole stores genetic information, and chloroplasts make proteins. Cells are the basic unit of structure of living things. Cells are the basic unit of function of living things. Cell parts such as chloroplasts are self-duplicating. Cells come from preexisting cells. 4. The invention of the compound light microscope enabled scientists to observe cells, helping them to 1) 2) 3) 4) determine the number of atoms in a molecule discover a basic similarity among organisms study the behavior of chordates develop techniques for growing plants in a laboratory 11. The cell represented below produces oxygen. 5. It was once thought that decaying meat turned into maggots (fly larvae). Careful experimentation by scientists demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that new individuals result only from 1) 2) 3) 4) genetic engineering reproduction and development nutrition and replication metabolic homeostasis Which structure allows the passage of this oxygen to the environment? 6. Which structures carry out life functions within cells? 1) tissues 3) organelles 2) organ systems 4) organs 1) A Page 1 2) B 3) C 4) D 12. In the diagram below, which letter indicates the part of the cell that carries out a function most similar to a function of the human excretory system? 15. What has to be properly functioning in a unicellular organism for homeostasis to be maintained? 1) organelles 3) guard cells 2) insulin 4) antibodies 16. Which letter in the diagram below indicates an organelle that functions primarily in the synthesis of long chains of amino acids? 1) A 2) B 3) C 4) D 13. The diagram below represents a cell of a green plant. 1) A 2) B 3) C 4) D 17. Which structures are found in every living cell? 1) 2) 3) 4) a plasma membrane and cytoplasm chloroplasts and mitochondria a cell wall and nucleus centrioles and chromosomes 18. Which structures in the diagram below enable the observer to identify it as a plant cell? Solar energy is used to produce energy-rich compounds in structure 1) A 2) B 3) C 4) D 1) A and B 3) A and C 14. The diagram below represents a plant cell. 2) B and C 4) B and D 19. A liver cell can make enzymes that a heart cell can not make because liver cells 1) 2) 3) 4) Which process takes place in structure A? 1) cellular respiration 3) digestion of fats 2) photosynthesis 4) protein synthesis Page 2 digest large, complex molecules contain more DNA than heart cells use different genes than the heart cells use remove carbon &oxide from blood 20. The diagram below represents an incomplete sequence of levels of organization. organelles tissues organs organ systems organism This sequence can be completed correctly by inserting 1) 2) 3) 4) "cells" between organelles and tissues "proteins" between tissues and organs "populations" between organs and organ systems "molecules" between organ systems and organisms Page 3 Biology (Living Environment) Name _________________ Class _________________ 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.
