Form A (Master Copy) Unit 1 Post Test: Structure and Function of Cells Unit 1 Post Test: Structure and Function of Cells » Form A (Master Copy) Directions: Please choose the best answer choice for each of the following questions. 1. 2. Which cellular process takes place ONLY in the chloroplast? 7. A. respiration A. protein synthesis B. active transport B. respiration C. photosynthesis C. replication D. passive transport D. photosynthesis Substances like oxygen pass through the cell without the use of energy and move from an area of high concentration to an area of low concentration. This process is called A. osmosis B. filtration 8. 9. The products of photosynthesis are carbon dioxide and water B. sugar and carbon dioxide 10. After starting in the cytoplasm of the cell, cellular respiration is completed in the endosytosis What is Life Science? A. The scientific studey of heredity. B. A way of learning about the natural world. What is NOT needed by all cells? A. food B. water A. ribosomes C. sunlight B. golgi bodies D. A way to get rid of waste. C. vacuoles 11. D. mitochondria DNA replication occurs during A. prophase B. cytokinesis 12. The two main process in which a cell absorb, release, and uses energy are fermentation and respiration B. digestion and photosynthesis A. carbon dioxide B. oxygen D. cellulose D. interphase A. Through the process of photosynthesis, which product is used by the plant cell? C. glucose C. metaphase 6. B. D. The study of taxonomy. D. lactic acid 5. diffusion C. The study of living things. C. sugar and oxygen 4. A. D. osmosis D. passive transport A. Which process moves water molecules across the membrane of a cell? C. exocytosis C. active transport 3. The process by which a cell captures thenerergy in sunlight and uses it to make food is called The cellular process in which materials move across the cell membrane from an area of high concentration to area of low concentration is called A. osmosis B. diffusion C. active transport C. photosynthesis and respiration D. passive transport D. aerobic and anaerobic respiration Go on to the next page » DataDirector Assessment ID: 18703 Page 1 of 3 © 2011 Houghton Mifflin Harcourt.

The cytoplasm divides. D. The chromosomes divide. 14. The picture above shows what happens when blood cells are placed in saltwater, blood plasma, and freshwater. What structure controls the flow of water into an dout of the cell? Which plant organelle uses light energy to produce sugar? A. chloroplast B. mitochondria C. nucleus 16. One difference between mitochondria and chloroplast is B. cell wall A. mitchondria use NADH whole chloroplasts make NADH. B. mitochondria produce water from oxygen while chloroplasts produce oxygen from water. C. mitochondria are only found in animal cells and chloroplasts are only found in plant cells. D. the Calvin cycle occurs in the mitochondria while the Krebs cycle occurs in the chloroplast. D. cell membrane 19. Animal structures contain all of the following structures except a A. nucleus and cytoplasm B. cell wall and chloroplast C. mitochondria and lysosomes Identify which organelle is represented by letter C in the picture. D. golgi apparatus and ribosomes 17. nucleus C. cytoplasm D. ribosome 15. A. __________________ is a jelly like substance, in both the animal and plant cell, containging important chemicals and acts like a mixture for the cell organelles. A. chloroplast B. cytoplasm A. nucleus B. vacuole C. ribosome D. golgi apparatus 20. What two organelles are found onlu in plant cells? C. mitochondria A. vacuoles and ribosomes D. vacuole B. chloroplast and ribosomes C. cell walls and chloroplasts D. endoplasmic reticulum and cell walls Go on to the next page » DataDirector Assessment ID: 18703 Page 2 of 3 © 2011 Houghton Mifflin Harcourt.

Compare the two different types of cells shown below. C. molecules D. organelles 22. A student proposed and followed this procedure to prepare a cheek smear to view under a microscope: 1. Using a clean toothpick, gently scrape the insie of your cheek. 2. Wipe the toothipick in the center of a slide. 3. To make a thin layer, hold the coverslip with one end against the slide and gently wipe the edge of the cover slip along the middle of the slide's surface. 4. Let the smear air dry. 5. Add a drop of stain to the center of the smear. 6. Gently set a coverslip over the smear. The diagram below shows what the student saw when she viewed the slide under a microscope. The shading shows where the stain stuck to the cheek material. • • • • Which cell is from a plant and which cell is from an animal? Explain how you can tell. Which letter or letters point to the chloroplasts? Which letter or letters point to the mitochondria? Compare the functions of chloroplasts and mitochondria in both types of cells. What structure are labels G and L pointing to? Describe the function of this structure in both cells. Identify and explain the important cellular process that structures G and L undergo in order to create new cells. Use words, numbers, and/or pictures to show your work. Enter your answer in the space provided. Part A Explain the purpose of scraping the inside of the cheek. Part B Identify the objects shown on the microscope slide. Explain what evidence you can use to identify these objects. Part C Identify a structure that was made more visible by the addition of the stain. Explain your answer. Part D Describe the function of the large stainded structure inside each cell. Stop! You Go have onfinished to the next thispage exam. » DataDirector Assessment ID: 18703 Page 3 of 3 © 2011 Houghton Mifflin Harcourt. All rights reserved.
