Chapter 7 Name Date Class 9 What characteristic of the plasma membrane is illustrated in this drawing Outside the cell bm The diagram below represents a cell in water. Explain why more water is moving out of the cell than into the cell. Oxygen Glucose Wastes Plasma membrane Water Inside the cell A selective permeability B phospholipid bilayer C fluid mosaic construction D impermeability to water Wastes Carbon dioxide bk While viewing a slide of rapidly moving sperm cells, a student concludes that these cells require a large amount of energy to maintain their activity. What organelles provide this needed energy A vacuoles B ribosomes C chloroplasts D mitochondria bl On a laboratory exam, a student is asked to determine if the cells under a microscope are plant cells or animal cells. What might the student look for A chloroplasts and a cell wall B ribosomes and vacuoles C a nucleus and ribosomes D a cell membrane and mitochondria Water Water Water molecule Solute A The concentration of solute in the cell is higher than it is outside the cell. B The concentration of water outside the cell is too great. C The concentration of solute outside the cell is higher than it is inside the cell. D The concentration of water inside the cell is greater than it is outside the cell. bn How can the cytoskeleton of a cell be described A framework and anchor for organelles B selectively permeable series of membranes C semifluid material D transport system bo Which movement of substances through a cell membrane against a concentration gradient requires energy A osmosis B diffusion C active transport D facilitated diffusion bp Which cell organelle contains coded directions for production of proteins A endoplasmic reticulum B lysosome C Golgi apparatus D nucleus Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. 14 CHAPTER 7 STANDARDIZED TEST PRACTICE
Chapter 8 Name Date Class 1 The process of photosynthesis converts which type of energy to chemical energy A heat B light C kinetic D potential 5 In the experiment shown below, which process occurring in the peas causes the drop of liquid to move to the left Drop of liquid Rubber stopper Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. 2 Two test tubes are filled with a solution of bromthymol blue. A student exhales through a straw into each tube, and the bromthymol blue turns yellow. An aquatic green plant is placed in each tube, and the tubes are corked. One tube is placed in the dark, and the other tube is placed in direct sunlight. The yellow solution in the tube in sunlight turns blue, while the one in the dark remains yellow. Which statement best explains why the solution in the tube placed in sunlight returns to a blue color A Oxygen was produced by photosynthesis. B Oxygen was removed by respiration. C Carbon dioxide was removed by photosynthesis. D Carbon dioxide was produced by respiration. Use the illustration below to answer questions 3 and 4. 1 2 3 Which reaction takes place in the thykaloid discs (1) of the chloroplast A carbon fixation B light-dependent reaction C light-independent reaction D Calvin cycle 4 Which reaction takes place in the stroma (2) of the chloroplast A carbon fixation B light-dependent reaction C light-independent reaction D photolysis Tube containing KOH solution (CO absorber) 2 A cellular respiration B digestion C photosynthesis D protein synthesis Oxygen Water-soaked peas 6 Which is a product of photosynthesis A ATP B glucose C water D carbon dioxide 7 The equation below represents a biological process Where is this process completed carbon dioxide + water glucose + oxygen A mitochondria B ribosomes C cell membranes D chloroplasts 8 Chlorophyll is the primary pigment in plant chloroplasts. It absorbs all wavelengths of light EXCEPT . A green B red C yellow D blue STANDARDIZED TEST PRACTICE CHAPTER 8 15
