1 Bacteria & Archaea Ms.Tanyaratana Dumkua Biology Department, MahidolWittayanusorn school
2 What is the bacteria?
3 epulopiscium.html << Small prokaryotic cell Range of diameter m Epulopiscium fishelsoni << Mycoplasma sp.
4 What is the different between prokaryote and eukaryote?
5 The important characteristic for classifying bacteria are : Cell membrane Shape Cell envelope & appendage Movement Photosynthesis Metabolism : aerobe, anaerobe, chemical product etc.
6 Bacteria : cell membrane Ester linkage (D-glycerol) Ether linkage (L-glycerol)
7 Bacteria : shape Bacillus : Rod Coccus : Sperical Spiral : vibrio (curve), spirillium, spirochete *Amorphus = mycoplasma >>
