Study Notes
Bacterial Characteristics
- Bacteria are a type of prokaryotic organisms.
Cell Division
- Bacteria primarily divide by a process called binary fission.
Bacterial Shapes
- Bacilli bacteria are typically rod-shaped.
- Spirochaetes bacteria are spiral-shaped.
Cellular Structure
- The peptidoglycan (also known as murein) layer in the cell wall determines the shape of a bacterium.
- The main characteristic of bacteria's cell wall is the presence of peptidoglycan.
Metabolic Process
- The main metabolic process of bacteria is fermentation, where they break down organic molecules to produce energy.
