Questions 1-23 __________ Mrs. Keadle JH Science Questions 24-35 _________ Name _________________________________ Date __________________________ Period _________ Cells Pre-Test 1 The food that you eat travels from your mouth, down your esophagus, into your stomach, and through your small and large intestines before your body rids itself of solid waste. As the food passes through your body, it is digested, and you get important nutrients from the food. Which of the following is the correct term used to describe a group of body parts working together to perform a specific function? A an organism B a tissue C an organ system D an organ 2 Living things are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a specific role or job to perform. Which of the following lists these levels in the correct order of organization from the simplest to the most complex? A cells, tissues, organs, organ systems, organisms B organisms, organ systems, organs, tissues, cells C tissues, cells, organs, organisms, organ systems D organs, organ systems, organisms, cells, tissues 3 All of the following are true EXCEPT: A Skin is an organ. B Tissues are made up of organs. C Each organ is made up of its own kind of tissue. D Tissues are made up of cell. 1 Cells Pre-Test Mrs. Keadle JH Science 4 All of the following are types of tissue except: 5 What types of organisms have cells with very large vacuoles? A muscle A animals B epithelial B bacteria C digestive C fungi D bone marrow D plants 6 Which phrase BEST describes the function of mitochondria? A located in the cytoplasm B bacteria-sized organelle 7 The three major parts of the circulatory system are the heart, the blood vessels, and the blood. The heart is an organ made up of specialized cells. Which of these functions can the heart perform that individual heart cells cannot? C converts energy for cell use A pumping blood D contains a folded inner membrane B producing waste C using energy D growing larger 2 Cells Pre-Test Mrs. Keadle JH Science 8 What function or process is common to all living things? 9 All living things, plant or animal, have one thing in common. Which of the following is the common thing? A photosynthesis B respiration C movement A They all have cells that are held up by cell walls. B They all have the same way to get water and food into their cells. D oxygenation C They all have cells. D They all have special cells that can do many different things. 10 In all living things, the presence of what structure supports the cell theory. 11 All of the following are characteristics of both living organisms and cells EXCEPT: A cell wall A remove waste from themselves B cell membrane B rely on chemicals for communication C vacuole C grow and die D chloroplast D extract energy from food 3 Cells Pre-Test Mrs. Keadle JH Science 12 Catherine needs to measure 2.5 mL of water to make a model of a cell in science class. Which of the following pictures best represents this measurement? A B C D 4 Cells Pre-Test Mrs. Keadle JH Science USE THE FOLLOWING DIAGRAM FOR THE NEXT FOUR QUESTIONS. 13 Which structures tell you whether this is a plant or animal cell? 15 Which cell structure functions like a school principals office? A II, V, VI A I B I, IV, V B II C I, III, IV C IV D I, IV, V, VI D VI 14 What kind of cell is this? 16 Identify the structure through which wastes exit the cell. A animal A I B plant B II C bacteria C III D virus D IV 5 Cells Pre-Test Mrs. Keadle JH Science USE THE FOLLOWING DIAGRAM FOR THE NEXT THREE QUESTIONS. You make a model of a cell in a large, rectangular, clear plastic container filled with the following: gelatin, green M&M’s, red licorice, several beans, one small inflated balloon, candy sprinkles, and an avocado seed. 17 What kind of cell is represented by your model? 19 How is using the model to study cells helpful? A plant A It is overly simplistic and not to scale B animal B It allows you to visualize something microscopic. C bacteria D fungi 18 What does the inflated balloon represent? C It is quickly assembled and easily disposed. D It helps you understand the relationship between structure and function of cell parts. A nucleus B mitochondria C vacuole D cell membrane 6 Cells Pre-Test Mrs. Keadle JH Science 20 Which numbered part of the plant cell shown above is a liquid like substance that fills the cell? A 1 B 2 C 3 D 4 21 What is the function of the cell wall? 22 In what plant cell structure is water stored? A to protect and support the cell A chloroplast B to perform different functions in each cell C to prevent water from passing through the cell. B cell wall C vacuole D cytoplasm D to prevent oxygen from entering the cell 7 Cells Pre-Test Mrs. Keadle JH Science 23 In what plant cell structure is water stored? 24 Which of the following scientists gave us a modern understanding of cell reproduction (mitosis)? A chloroplast A Schleiden B cell wall B Schwann C vacuole C Virchow D cytoplasm D all of the above closed jar open jar open jar after a few days Ashley repeated Francisco Redi’s experiment for a spontaneous generation project. She placed meat in two identical jars. She placed a stopper in the top of one jar and left the other uncovered. After a few days, Ashley observed young flies (maggots) on the meat in the open jar. There were no flies in the sealed jar. 25 What hypothesis was Ashley trying to test? A Decaying meat produces maggots B Maggots prefer one type of meat over another. C Maggots need a certain temperature to appear. D Plastic wrap keeps meat from spoiling. 8 Cells Pre-Test Mrs. Keadle JH Science 26 During mitosis, DNA is copied and passed on to new cells. In which part of the cell is this hereditary material located? A cell membrane B cytoplasm C nucleus D cell wall 27 During which phase of mitosis do the two separate nuclei appear? A telophase B anaphase C early prophase D late prophase 28 Based on the process shown in the diagram above, which of the following is a valid conclusion? A First the cells divide, then mitosis occurs, and then the chromosomes are copied. B First mitosis occurs, then the cells divide, and then mitosis occurs again. C First the chromosomes are copied, then endocytosis occurs, and then the cells divide. D First the chromosomes are copied, then mitosis occurs, and then the cells divide. 9 Cells Pre-Test Mrs. Keadle JH Science 29 If you damage your skin, what process do your cells use to make repairs (scabs and new skin)? 30 What would happen to an organism if it’s cells could no longer undergo mitosis? A nothing A spontaneous generation B it would grow larger B mitosis and cytokinesis C it would stop growing and die C meiosis D it would shrink D the cell theory 31 Beginning with interphase, what are the phases of mitosis in order? 32 Which drawing represents interphase? A 4 A telophase, anaphase, metaphase, prophase B 3 B anaphase, metaphase, prophase, telophase C 2 C prophase, anaphase, metaphase, telophase D 1 D prophase, metaphase, anaphase, telophase 10 Cells Pre-Test Mrs. Keadle JH Science 33 In which phase of mitosis do cells spend 95% of their time? A metaphase 34 After mitosis is complete, how are the two cells alike? A they both have double the chromosomes B anaphase C interphase B they are identical copies of each other D prophase C the new cell has half the DNA D one cell is newer than the other 35 Your body has a layer of skin that protects it from the environment. This layer of skin is made up of many individual skin cells. Explain where all the cells came from and how two individual cells share the same traits. 11 Cells Pre-Test
