Biological basis of Gram staining
- Bacteria have both of cell wall and cell membrane
- Human and other animal cells have no cell wall
- Plant cells have cell wall
- Some bacteria have thick cell wall without outer membrane
- Other bacteria have thin cell wall with outer membrane
- Cell wall contains a layer of Peptidoglycan
- Thick peptidoglycan layer catches and keep crystal violet with iodine
- Outer membrane catches crystal violet with iodine but easily lose them by ethanol rinsing
