MORPHOLOGY AND Notes CLASSIFICATION OF BACTERIA
1 MORPHOLOGY and CLASSIFICATION of BacteriaMICROBIOLOGYMODULEM icrobiologyNotes1 MORPHOLOGY ANDCLASSIFICATION OF INTRODUCTIONM icroorganisms are a heterogeneous group of several distinct classes of livingbeings. Based on the difference in cellular organization and biochemistry, thekingdom protista has been divided into two groups namely prokaryotes andeukaryotes. BACTERIA and blue-green algae are prokaryotes, while fungi, otheralgae, slime moulds and protozoa are eukaryotes. BACTERIA are prokaryoticmicroorganisms that do not contain chlorophyll. They are unicellular and do notshow true branching, except in higher BACTERIA like reading this lesson, you will be able to:zdescribe the structure of Prokaryotic and Eukaryotic cellzexplain the size of bacteriazclassify BACTERIA based on the shape and arrangementszdescribe the structure of bacterial cell wallzdescribe the phases of Growth curvezexplain the factors affecting the growth of PROKARYOTESThe prokaryotic cells have the following characteristics such aszNo organelles, all the action takes place in the cytosol or cytoplasmicmembraneMICROBIOLOGYMODULEM orphology and CLASSIFICATION of BacteriaMicrobiology 2 NoteszMost BACTERIA possess peptidoglycan, a unique polymer that makes itssynthesis a good target for antibioticszProtein synthesis takes place in the cytosol with st
lesions (from actis meaning ray and mykes meaning fungus) 7. Mycoplasmas are bacteria that are cell wall deficient and hence do not possess a stable morphology. They occur as round or oval bodies and as interlacing filaments. Fig. 1.3: Shapes of bacteria.
