Biodiversity monera

Biodiversity -the variability

• Genetic diversity
• species diversity
• ecosystem diversity

1.kingdom monera     prokaryotes /unicellular/asexual /size 70/single chromosomes /circular    /                                  motile  / DNAplasmid/Flagella /Pili/Capsule(polysaccharides)

Eubacteria-         E.coli /Cynobacteria(blue green algae)/Nostoc (nitro-fixation)

Archaebacteria-most chemoautotrophs (oxidation of inorganic material)-Sulfolubus

                         Methanogens produce methane gas from O2+Co2
                         Halophiles High salt concentration
Difference -cell wall (Eubacteria gt peptidoglycan)
                   -histone protein(eubacteria no have)
                   -membrane lipid (unbranced carbon chain)
                   -habitat(eubacteria extreme)
classification of monera -1)cell shape
                    coccus   -Pneumococcus(single)-staphlocuccus(cluster )-Stretococcus-Chain
                    bacillus(rod shape)-e.g. E.Coli

Importance of monera

1. Recycling of chemical element in ecosystem (nitrogen fixation)
2. Pathogenic 
3. Symbiotic relationship(milk digestion)
4. Technology and medical research
5. Food processing(yogurt)
