Biology II AP Objectives

Topics:

7. Structure & Function of Cell Membranes
   • What is the current model of the molecular architecture of membranes?
   • How do variations in this structure account for functional differences among membranes?
   • How does the structural organization of membranes provide for transport and recognition?
   • What are various mechanisms by which substances cross membranes?
   1. Explain how scientists used early experimental evidence to make deductions about membrane structure and function
      • Davson-Danieli, J.D. Robertson, S.J. singer, and G.L. Nicolson
   2. Describe the structure of the fluid mosaic model of the plasma membrane
   3. Describe diffusion and osmosis and factors that contribute to them
   4. Distinguish between passive and active transport
   5. Describe the types of pumps and channels found in the membrane
   6. Explain how and when receptor-mediated endocytosis would work
   7. Explain the different between, phagocytosis, and pinocytosis

Time Range:
7 days

Suggested Teaching Strategies:

• Students will read and take their own notes on the chapter (maybe in outline form)
• Science as a Process: Lecture on historical discovery of cell membrane
• Lecture on diffusion, osmosis, passive, activity transport, phagocytosis and pinocytosis
• Lecture on pumps and channels
• Students take notes on lecture (maybe in outline form)
• Students will fill out crossword puzzle that uses terms from the chapter
• Students will fill out chapter study guide to compliment their lecture and board notes
• Students will fill out worksheet on fluid mosaic model
• Reading and questions worksheet on Cystic Fibrosis
• Internet usage and determine reliability of a site's information
• Worksheets on types of search engines
• Critical Thinking: Ask students to do internet search to find out the process of kidney dialysis, and what is the leading cause of kidney disease
• Critical Thinking: Students will use computer and do activity on 8.0 thru 8.6 on Membrane Structure and Function on CD Rom from Campbell's Biology
• Critical Thinking: Building a Fluid Mosaics Model of plasma membrane
