Bacteria

• Bacterial flagellum
  • Most commonly, one flagellum creates a "run and twiddle" movement where bacteria can achieve [[chemotaxis]]
  • [[Spirochaeta]] have their flagellum throughout the inside of the cell, which allows movement through viscous materials
• By default, bacteria are Gram-negative, except for [[Fermicutes]]: Gram-negative bacteria form a [[symplesiomorphy]]
