Lecture Outline for Campbell/Reece Biology, 7th Edition, ? Pearson Education, Inc. 11-1 Chapter 11 Cell Communication Lecture Outline Overview: The Cellular Internet ? Cell-to-cell communication is absolutely essential for multicellular organisms. ? Cells must communicate to coordinate their activities. ? Communication between cells is also important for many unicellular organisms. ? Biologists have discovered universal mechanisms of cellular regulation involving the same small set of cell-signaling mechanisms. ? The ubiquity of these mechanisms provides additional evidence for the evolutionary relatedness of all life. ? Cells most often communicate by chemical signals, although signals may take other forms.

Chapter 11 ? Cell Communication Cell Identity ?? tissues?- highly specialized cell groups found only in multicellular organisms? each tissue cell performs only the functions of that tissue cells gain their identities by controlling the expression of the genes only specific sets of genes are turned on tissue-specific identity markers?- mark cell surfaces as a particular type cells of the same tissue type form connections when they recognize each other glycolipids?- lipids w/ carbohydrate heads accounts for majority of tissue-specific surface markers responsible for differences between blood types MHC proteins?- distinguishes cells of the organism from foreign cells single-pass proteins anchored in the plasma membrane immune system cells destroy cells w/o the correct identity markers
