1. Describe the role and importance of the cell membrane. What is meant by "the cell membrane is semipermeable?" 2. Describe the basic structure of the cell membrane with regard to specific molecules. 3. Why is the cell membrane often referred to as a "fluid-mosaic"? 4. What is the function and purpose of the proteins embedded in the cell membrane? 5. Please compare and contrast passive transport and active transport. 6. Describe what is taking place during diffusion. Is this a form of passive or active transport? Explain your reasoning. 7. Describe what osmosis is. Is this a form of passive or active transport? Explain your reasoning. 8. What are the similarities and differences between diffusion and facilitated diffusion? 9. Describe three ways that cells perform active transport.

1. What are the constituents of the plasma membrane? 2. What are the functions of these constituents (roles they play)? 3. What is dual polarity, and which molecule has it in the plasma membrane? 4. What is the lipid raft? 5. What is passive transport? What is active transport? Describe both types of passive transport and also active transport. 6. Understand hyper/hypo/isotonic solutions and how osmosis responds to them (where does the water go?). 7. Osmosis vs. diffusion.

What properties make endospores resistant to processes that normally kill vegetative cells? 7. What keeps the nucleus suspended in the cell? 8 How are mitochondria similar to prokaryotic cells? 9 What are the similarities between chloroplasts and prokaryotic cells?
• Passive Membrane Transport: What kinds are there, how do they work, what substances are commonly transported with each? • Active Membrane Transport: Why is it called "active" - how is it different from passive transport, what are the different types, how does each operate, what substances are commonly transported with each, what is symport & antiport, what are solute pumps, how does the sodium-potassium pump work, how does glucose get pulled into the cell?
