Cell Transport Review - Answers

Name Cellular Transport Review OSMOSIS: Label the pictures below (isotonic, hypertonic, or hypotonic environments) INPO TONIC HYPERTONI Block ISO TONIC 1. Mtonic means there is a GREATER concentration of solute molecules OUTSIDE the cell than inside. 2. HYPO tonic means there is a LOWER concentration of solute molecules OUTSIDE the cell than inside. 3. 150 tonic means there is the SAME concentration of solute molecules outside the cell as inside. * * MULTIPLE CHOICE: Circle the answer(s) that best completes the sentence. 1. The substance that dissolves in the liquid to make a solution is called the A. diffuser C. solute B. solvent D. concentrate 2. During diffusion molecules tend to move A. up the concentration gradient (B) down the concentration gradient C. from an area of lower concentration to an aren of higher concentration D. in a direction that doesn't depend on concentration 3. When the concentration of a solute is the same throughout a system, the system has reached A. maximum concentration C. osmotic pressure B. homeostasis (D.Jequilibrium 4. The diffusion of water ncross a selectively permeable membrane is called A. active transport Cosmosis A. active B. facilitated diffusion D. phagocytosis 5. Phagocytosis, pinocytosis, and exocytosis are all kinds of transport. B. passive 6. Energy for active transport comes from a cell's A. Golgi complex B. nucleus C. mitochondria D. lysosomes 7. transport requires energy from ATP to move substances across membranes. A. Passive B. Active 8. A cell must expend energy to transport substances using A. diffusion C. osmosis B. facilitated diffusion andocytosis 1 9. White blood cells engulf, digest, and destroy invading bacteria using Facilitated diffusion B. pinocytosis C.phagocytosis D. osmosis 10. All of the following are kinds of passive transport EXCEPT A. Diffusion B. facilitated diffusion C. osmosis (D. phagocytosis B. phagocytosis D. osmosis 11. Endocytosis that brings in small dissolved molecules (solutes) and fluids is called A. Pinocytosis C. facilitated diffusion 12. Golgi bodies use A. ion channels C. pinocytosis to transport molecules out of cells. B, phagocytosis (D. cxocytosis 13. The pressure exerted by water moving during osmosis is called pressure. A. tonic C. selectively permeable 13. diffusion D. osmotic 14. Placing an animal cell in a hypotonic solution will cause water to A. move into the cell B. move out of the cell 15. When molecules move DOWN the concentration gradient it means they are moving from A, an area of low concentration to an area of higher concentration B. an area of high concentration to an area of lower concentration 16. Gases like Na+ and K+ move across cell membranes using A. endocytosis C. diffusion B. ion channels D. facilitated diffusion Completion: Complete the transport terms. 1. Active transport requires ENER to move molecules across membranes. 2. ATP is the molecule that provides the energy for active transport. 3. Golgi bodies use EXOCYT6515 to release molecules outside the cell. 4. DIFFUSICmoves oxygen and carbon dioxide molecules from a high concentration to a low concentration across membranes. 5. This organelle converts glucose into ATP for active transport is the MITOCHUNDRIA 6. Water moves across membranes by OSMOSIS. 7. A small membrane sac used to transport substances during exocytosis & endocytosis -VESICLE 8. Kind of endocytosis that takes in small dissolved molecules (solutes) or fluids PINOCY 9PASSIVE transport does NOT REQUIRE energy. 10. During FACILITATE diffusion carrier proteins grab glucose molecules, change shape, and flip to the other side of the membrane, like a revolving door. 2 11. A cell placed in an ISOTONIC solution neither swells or shrinks because the concentration of molecules outside the cell is the same as inside.. 12. A solution in which there is a HIGHER solute concentration OUTSIDE the cell than inside -HYPERTONIC. 13. A CONCENTRATION O DIENT forms whenever there is a difference in concentration between one place and another. 14.Pinocytosis, phagocytosis, and Na-K pumps are all kinds of ACTIVE transport because they use energy to move substances across membranes. 15. A solution in which the concentration of molecules outside the cell is LOWER than inside HYPOJONIC 16A SODIUM POTASSIUM PUMP uses ATP to move three Na' ions out of a cell while it moves two Kions in 17. Pinocytosis & phagocytosis are both kinds of END G C YIO515 18. When molecules move from high to low along a concentration gradient we say they are moving "Dew" the gradient. 19. OSMOTIC pressure is caused by water inside a plant cell pushing against the cell wall. 20. The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called PLASMOLYSIS. 21. White blood cells use PHAGOCYTOSIS to engulf and destroy bacteria that glycoproteins recognize as "not self". the 22. The swelling and bursting of animal cells when placed in a hypotonic solution is called CYTOLYSIS.
