Study Notes
Bacterial Cell Characteristics
- Bacterial cells range in size from 0.5 to 5.0 μm in diameter.
Cell Wall Composition
- The cell wall of most bacteria is composed of peptidoglycan (also known as murein).
- Peptidoglycan is a unique polymer found in the cell wall of prokaryotic organisms.
Bacterial Size and Morphology
- The smallest known bacteria mentioned is Mycoplasma, with a size range of 0.1 to 1.0 μm in diameter.
- Mycoplasma has a spherical or ovoid morphology.
- 'Cocci' refers to a type of bacterial morphology characterized by spherical or ovoid shapes.
Cell Structure
- The three-layered structure of bacteria is composed of the outer membrane, peptidoglycan layer, and cytoplasmic membrane.
