Common mistakes in Monera - bacteria, archaebacteria and their shapes
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Treating all autotrophic bacteria as photosynthetic.
- Answers 'no cell wall', confusing archaebacteria with Mycoplasma.
- Assigns nitrogen fixation to photosynthesis or files cyanobacteria under archaebacteria.
- Calls the ammonia-oxidiser a heterotroph because it uses a chemical, forgetting that chemosynthetic autotrophs still fix CO2.
