Lesson 6: Movement of ions and molecules
Selective membrane - Ionic separation, nutrients in and waste out
Phospholipid bilayer - Proteins and lipids dissolved in it, 7nm thick
Fluid and self sealing - Allows cell division, endocytosis and exocytosis
Key terminology
Polar, non polar, hydrophilic, hydrophobic, amphiphatic, amphipathic
