Study Notes
Bacterial Structure
- Peptidoglycan (also known as murein) is a unique structural feature of bacteria, providing cell wall rigidity and maintaining cell shape.
- The most elemental structural property of bacteria is the presence of a cell wall.
Bacterial Shapes
- Spiral (helical) shape is a typical shape of bacteria, along with rod-shaped (bacilli) and spherical (cocci) shapes.
- A square shape is NOT a typical shape of bacteria.
Species Characteristics
- The presence of specific structural features, such as fimbiae, flagella, and capsules, is characteristic of a given bacterial species.
Complex Life Cycles
- Some bacteria, such as certain species of Bacillus, exhibit a complex life cycle feature, which involves the formation of highly resistant endospores that allow them to survive extreme conditions.
