Hematoxlyin and Eosin - 1. Hematoxylin = basic dye stains acidic molecules like nucleus, DNA, RNA 2. Eosin = acidic dye stains basic molecules like cytoplasm Plasma membrane - lipid bilayer in which proteins are embedded -has 2 layers 1. hydrophilic = head 2. hydrophobic = tail 2 types of proteins in plasma membrane: 1. Integral membrane proteins = inside the plasma membrane 2. Peripheral membrane proteins = outside of the membrane
