300 What are the main functions of the cell membrane and how does its structural design serve its function?
300 What are the criteria for passive and active transport and what are the various mechanisms for each?
400 1. Resources needed in the cell as well as wastes that must exit the cell
400 2. The role of the plasma membrane as a barrier
400 3. Movement of materials into and out of the cell -- 
400             Passive systems:  diffusion, osmosis, facilitative diffusion
400             Active systems:  active transport, endocytosis, exocytosis

500 Students in Biology will develop the ability to:
500 1. Describe the structure of the cell membrane and relate it to its function,
500 2. Explain what is needed in the cell and what must exit the cell,
500 3.  Describe and offer examples of the various modes of transport into and
500    out of the cell:
500               A. Passive transport: diffusion, facilitated diffusion, osmosis
500               B. Active transport: protein pumps, bulk transport (endocytosis by pinocytosis, phagocytosis, exocytosis and the role of vesicles).
