What are the components of a bacteria cell wall?
1. Small cell size (usually 0.2 - 10 micrometers) 2. DNA organized in nucleoid throughout the cytoplasm 3. Small genomes (0.5 - 15 million base pairs) 4. Circular chromosomes, although may have multiple circular and linear chromosomes 5. Chromosomes replicate and segregate during cell growth 6. Few intracellular membranes such as thyakloids of photosynthetic bacteria - cyanobacteria 7. No intracellular endosymbiotic organelles 8. Cell wall composed of peptidoglycan 9. Rotary flagella for motility, driven by proton motive force.
