Cell Transport Study Guide 1. Draw a phospholipid. Label the phosphate head and lipid tails. Label which part is hydrophilic/hydrophobic 2. List the 2 parts of the cell membrane 3. What does it mean to be selectively permeable? 4. Why is the cell membrane described as a bilayer? 5. Why is the cell membrane described as a fluid mosaic model? 6. DRAW PICTURES!!!! A. A cell that is 70% water, 5% protein and 2% sugar is put into a solution that is 65% water, 7% protein and 3% sugar. Water will move __________________. Sugar will move __________________. Protein will move _________________. B. A cell that is 70% water, 5% protein, and 2% sugar is put into a solution that is 75% water, 3% protein, and 1% sugar. Water will move __________________. Sugar will move __________________. Protein will move _________________. C. A cell that is 70% water, 5% protein, and 2% sugar is put into a solution that is 70% water, 5% protein, and 4% sugar. Water will move __________________. Sugar will move __________________. Protein will move _________________. OSMOSIS ( isotonic, hypertonic, or hypotonic = bonus words) *remember that the black dots cannot pass through the membrane – the open space represents water…which can pass through the membrane. 7. Draw an arrow to indicate the movement of water, in each diagram (into/out of cell), and then tell what happens to each cell (stays the same, shrink, swell) ______________ ______________ _________________ 8. If the solute (dots) in this diagram is unable to pass through the dividing membrane, what will happen? A. the water level will rise on the right side of the tube B. the water level will rise on the left side of the tube C. the water level will stay equal on the two sides COMPARE/ CONTRAST the kinds of transport 9. Fill in the table What does it use to help: Active or Transport Passive proteins? Vesicles? Needs no help? Does it require energy? Molecules move which way? High to Low or Low to High? SIMPLE DIFFUSION FACILITATED DIFFUSION OSMOSIS SodiumPotassium (Na+ -K+) pump ENDOCYTOSIS EXOCYTOSIS 10. Define what it means to be a specialize/differentiated cell. Give 3 examples of differentiated cells. 11. NUMBER AND NAME THESE LEVELS OF ORGANIZATION IN THE CORRECT ORDER FROM SIMPLEST TO MOST COMPLEX. _____ ______________ _____ _______________ _____ _______________ _____ _______________ _____ _______________ _____ ______________
