Study Notes
Capsule Function
- The capsule is a protective outer layer in some bacteria
- It is responsible for resisting phagocytosis, which is the process where immune cells engulf and destroy bacteria.
Gram Staining
- Gram staining is a technique used to differentiate bacteria based on their cell wall structure.
- Gram-positive bacteria have thicker peptidoglycan cell walls, which retain the crystal violet stain, making them appear violet under a microscope.
