What is the Difference Between Bacteria and Mollicutes?
🆚 Go to Comparative Table 🆚Bacteria and Mollicutes are both single-celled prokaryotic organisms, but they have some key differences:
- Cell Wall: Bacteria have a rigid cell wall composed of peptidoglycan, while Mollicutes lack a cell wall.
- Size: Mollicutes are smaller in size compared to bacteria, typically around 0.2–0.3 μm (200–300 nm).
- Genome Size: The genome of Mollicutes is smaller than that of bacteria.
- Lifestyle: Mollicutes are mostly parasitic organisms, depending on their host for nutrients, while bacteria have various lifestyles, including free-living and symbiotic forms.
- Gram Staining: Both bacteria and mollicutes can be Gram-positive.
In summary, the main differences between bacteria and mollicutes are the presence of a cell wall, size, genome size, and lifestyle. Bacteria have a peptidoglycan cell wall, are larger, and can have various lifestyles, while mollicutes lack a cell wall, are smaller, have a smaller genome, and are mostly parasitic.
Comparative Table: Bacteria vs Mollicutes
Here is a table highlighting the differences between bacteria and mollicutes:
Characteristic | Bacteria | Mollicutes |
---|---|---|
Definition | Single-celled prokaryotes with a peptidoglycan cell wall | Single-celled organisms without a cell wall |
Taxonomic Classification | Domain | Class |
Size | 0.5 to 2.0 µm | 0.2 to 0.3 µm |
Cell Wall | Made up of peptidoglycan molecules | None |
Genome | 0.6 to 0.8 megabases | 578 to 2500 kilobases |
Lifestyle | Free-living, commensals, or parasites | Parasites of plants or animals |
Bacteria are single-celled prokaryotes that have a peptidoglycan cell wall, while mollicutes are single-celled organisms without a cell wall. Bacteria have a larger genome compared to mollicutes, and they can have various lifestyles, such as being free-living or existing as commensals or parasites. On the other hand, mollicutes are all parasites of either plants or animals.
