Bacteria

Bacteria Properties

• Contains cell wall (diff from plant wall)
  • Made of peptidoglycan, which is a biological polymer
    • Chain Structure:
  • Provides structure for bacteria
• May be photosynthetic (cyanobacteria) which are autotrophs

Gram Staining

• Used to differentiate bacteria (unique method for bacteria)
• 
• Involves a dye that is used to stain bacteria:
  • Gram-Positive Bacteria (Purple)
    • Thick peptidoglycan cell walls that absorb dye more effectively
  • Gram-Negative Bacteria (Pink)
    • Thinner peptidoglycan cell walls that repel dye
