Study Notes
Bacteria Shape Classification
- Coccus, bacillus, and spirillum are common shapes of bacteria.
- "Vibrio" (comma-shaped) and "spirochete" (corkscrew-shaped) also classify bacteria.
- "Cuboid" is NOT a recognized shape classification of bacteria.
Bacilli Bacteria
- Bacilli are rod-shaped bacteria, characterized by their elongated, cylindrical form.
- They play significant roles in various ecological and health-related processes.
Bacterial Arrangement
- Staphylococci refers to bacteria that occur in grapelike clusters.
- This arrangement results from the division of the cells in multiple planes.
Determinants of Bacterial Shape
- The shape of a bacterium is primarily determined by its cell wall structure and composition.
- Cellular processes and genetic factors also influence the morphology.
Size Range of Bacteria
- The size of bacteria typically ranges from 0.5 to 5 micrometers.
- Some specialized species can be even smaller or larger, influencing their visibility under a microscope.
