Study Notes
Energy Sources
- Phototrophs use light as a source of energy.
- Chemotrophs use chemical compounds as an energy source.
Bacterial Shapes
- Bacteria can have different shapes, including:
- Cocci (spherical shape)
- Bacilli (rod-shaped)
- Spiral (helical shape)
- Vibrio (comma-shaped)
Bacterial Arrangements
- Bacterial cells can be arranged in different ways, such as:
- Single cells
- Pairs (diplococci)
- Chains (streptococci)
- Clusters (staphylococci)
- Bacteria can form biofilms, which are communities of bacteria that adhere to surfaces and are protected by a matrix.
