Chapter 5: Membrane Structure and Function AP Biology Fluid Mosaic Model Video The Basics ● The structure of cell membranes results in selective permeability ● Cell membranes separate the internal environment of the cell from the external environment. ● Selective permeability is a direct consequence of membrane structure as described in the fluid mosaic model. Fluid Mosaic Model 1. Singer and Nicolson (1972) introduced this model 2. Embedded proteins are scattered throu...

CHAPTER 1 What are the 5 characteristics that distinguish life from non-life? • Organized by Cells • Use Resources for Energy • Grows and Develops • Responds to stimulus or Environmen t • Reproduce Scientists and their contributions • Robert Hooke- Created first microscope, (only 30X), first guy to see cells • Anton Van Leeuwenhoek – made much more powerful microscope (up to 300X) could see animalcules... also saw blood cells and sperm cells • Rudolph Virchow- proposed that all...
