Cellular Transport Review Answer Keys

Cell Transport Review Worksheet Complete the table by checking the correct column for each statement: Hypotonic solution Statement Isotonic solution Hypertonic solution Causes a cell to swell Doesn't change the shape of a cell The cell membrane forms around another substance, for example, how the amoeba gets its food When molecules move from areas of high concentration to areas of low concentration Label the diagrams of cells using the following terms: diffusion, active transport, osmosis, equilibrium. The arrows show the direction of transport. You may use the terms more than once! Causes osmosis Causes a coll to shrink Watch the term with its correct description: fattended energy b facilitated diffusion c. endocytosis passive transport active transport exocytosis channel protein g. carrier protein Transport protein that provides a tube-like opening in the plasma membrane through which particles can diffuse is used during active transport but not passive transport Process by which a cell takes in material by forming a vacuole around it Particle movement from an area of higher concentration to an area of lower concentration Process by which a cell expels large amounts of waste A form of passive transport that uses transport proteins Particle movement from an area of lower concentration to an area of higher concentration Transport protein that changes shape when a particle binds with it Match the term with its correct description: High Active Transpo osmosis 20 мин Low CO, levels Active diffusion Osmosis Practice Activity 1040 chitusia Osmosis is the diffusion of water from an area of high concentration to an area of low concurbation, Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell Complete the centences below by comparing the concentration of the water inside the cell and the concentration outside the coll a transport protein b. active transport d. passive transport exocytosis e. osmosis equilibrium c. diffusion Kendocytosis The diffusion of water through a cell membrane The movement of substances through the cell membrane without the use of cellular energy a. Water wil flowst (no the coll. out of the cell, in both directions 5% NaCl 95% H₂O 95% NaC 5% HO b. The cell will burst, stay the same) Shank Water will few born directing the cell out of the coll, in both directions) ahrink Used to help substances enter or exit the cell membrane 5% NaCl 95% HO 5% NaCl When energy is required to move materials through a cell membrane When the molecules of one substance are spread evenly throughout 85% HO The call will Same (shok borst stay the same) another substance to become balanced A vesicle fuses (becomes a part of) the cell membrane and the contents are released Cellular Transport Review-PART ONE Draw and label the cell membrane: (include: protein, carbohydrate, phospholipids, hydrophobic and hydrophilic) Ye carbonydrate Prok 19989 りか 1988-Hydrophilic 998 Phospholipid bi-layer Hydrophobic Match the following to review passive transport: Pick the BEST answer. You may use the letters more than once! A. Diffusion 1. D Diffusion across a biological membrane B. Osmosis 2. A Any spread of molecules from an area of high concentration to an area of low concentration. C. Facilitated Diffusion D. Passive Transport 3. C Diffusion with the help of a transport protein. 4. B Diffusion of water across a selectively permeable membrane. 5. A.B.C The three types of passive transport. 6. D Does not require any energy and moves substances from an area of high concentration to an area of low concentration. ate whether water will: enter the cell (IN), leave the cell (OUT), or move in both directions equally (EQUAL) to review osmosis: 7. Out Cell is exposed to hypertonic solution. 8. Out Cell is placed in salt water. 9. Equabell is in isotonic solution. 10. IN Unicellular organism is placed in pure water for examination under the microscope, 11. Solute concentration of the cell is greater than solute concentration of surrounding fluid. 12. IN Cell is exposed to hypotonic solution. 13. Out Cytoplasm is more dilute than surrounding solution. Complete the table to review osmosis: How does an animal cell respond? How does a plant cell respond? Hypertonic 14. Shrink 15. Shrink (Plasmolysis tonic 16. Swell Burst 17. Swell Isotonic 18. Same 19. Same Cellular Transport Review PART TWO Match the following to review active transport: Pick the BEST answer. You may use the letters more than once! A. Endocytosis 20. C Cell drinking B. Exocytosis 21. D/AHow a cell would capture a bacterium C. Pinocytosis 22. C. The two types of endocytosis D. Phagocytosis 23. D Cell eating 24. A Allows cells to swallow large quantities of a particular substance (could be liquid or solid) 25. B Allows cells to dump large quantities of a particular substance Label the following to review cellular transport: 26. exocytosis 27. endocytosis.
