Transcript
Read pages 184-189 Answer the following questions: 1. What are some of the functions of the cell membrane? 2. What is diffusion? Does it move from a high to low concentration, or a low to high concentration? 3. What is osmosis? 4. What does it mean to be selectively permeable? 5. Describe the basic structure of a cell membrane. 6. Sketch a picture of a phospholipid bilayer. 7. Which type of macromolecule is found in the membrane and allows substances to pass in and out of the cell? 8. How does active transport differ from diffusion? Be specific.
