- 1. Multiple ChoiceWhich structure is common to plant and animal cells?central vacuolechloroplastwall made of cellulosemitochondrion
- 2. Multiple ChoiceWhich of the following is major cause of the size limits for certain types of cells?evolutionary progression in cell size; more primitive cells have smaller sizes.the need for sufficient surface area to support the cell's metabolic needs.limitation on the strength and integrity of the plasma membrane as cell size increasesthe difference in plasma membranes between prokaryotes and eukaryotes
- 3. Multiple ChoiceWhite blood cells engulf bacteria through what process?pinocytosisosmosisphagocytosisexocytosis
- 4. Multiple ChoiceA patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, distilled water-equal to the volume of blood lost-is transferred directly into one of his veins. What will be the most probable result of this transfusion?The patient's red blood cells will shrivel up because the blood fluid has become hypertonic compared to the cells.The patient's red blood cells will shrivel up because the blood fluid has become hypotonic compared to the cells.It will have no unfavorable effect as long as the water is free of viruses and bacteria.The patient's red blood cells will swell because the blood fluid has become hypotonic compared to the cells.
- 5. Multiple ChoiceA biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, whereas organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively,mitochondria and chloroplasts.peroxisomes and chloroplasts.chloroplasts and peroxisomes.chloroplasts and mitochondria.

- 8. Multiple ChoiceAll of the following are part of a prokaryotic cell excepta plasma membraneDNAan endoplasmic reticulumribosomes
- 9. Multiple ChoiceWhen a plant cell, such as one from a tulip stem, is submerged in a very hypotonic solution, what is likely to occur?The cell membrane will lyse.The cell will burst.The cell will become turgid.Plasmolysis will shrink the interior.
- 10. Multiple ChoiceThe body's automatic tendency to maintain a constant and optimal internal environment is termedestivation.homeostasis.physiological chance.static equilibrium.
- 11. Multiple Choice
Which way would the purple molecules move through the semi-permeable membrane?From the A side to the B-sideFrom the B side to the A sidenone of the purple molecules would movethey would move equally back and forth in a state of dynamic equilibrium - 12. Multiple ChoiceWhich form of active transport is being shown? (Inside of the cell is tan colored)Facilitated DiffusionExocytosisEndocytosisReceptor-mediated endocytosis
- 13. Multiple ChoiceThe difference between osmosis and diffusion is thatdiffusion is passive transport, whereas osmosis is active transportonly in diffusion do molecules move from areas of high concentration to areas of low concentrationosmosis is the opposite of diffusion and only involves the movement of waterosmosis refers specifically to the movement of water, whereas diffusion refers to the movement of any type of molecules
- 14. Multiple ChoiceWhich of the following contains the highest water potential?ABCD
- 15. Multiple ChoiceIf a student was going to draw an arrow indicating the solution from the highest water potential to the lowest water potential, the arrow would be pointingfrom the left to the rightfrom the right to the left

- 17. Multiple ChoiceWhich of following correctly represents the packaging of a protein within a vesicle .1234
- 18. Multiple ChoiceWhat is the approximate sucrose concentration in the potato core?.43 M.30 M0.0 M1.0 M
- 19. Multiple ChoiceWhich statement about diffusion is false?Diffusion does not require ATPSimple diffusion depends upon specific carrier proteinsIn diffusion, molecules move from areas of greater concentration to areas of lesser concentrationDiffusion continues until the molecular concentrations are in equilibrium
