MICROBES NAME: JAVIYA RUCHIT chirag jayswal
Taxonomy Organizing, classifying and naming living things Formal system originated by Carl von Linné ( ) Identifying and classifying organisms according to specific criteria Each organism placed into a classification system chirag jayswal
Taxonomy Domain Kingdom Phylum Class Order Family Genus species chirag jayswal
3 Domains Eubacteria true bacteria, peptidoglycan Archaea odd bacteria that live in extreme environments, high salt, heat, etc. (usually called extremophiles) Eukarya have a nucleus & organelles (humans, animals, plants) chirag jayswal
MICROBES Microscopic life forms that cannot be seen by the unaided eye May be plant or animal May be prokaryotic or eukaryotic chirag jayswal
Importance of Microbes Pathogenic Help cure / prevent disease Break down organic matter to inorganic forms (decompose, recycle) Autotrophs (inorganics) Animals (organics) Decomposers (inorganics, external digestion!) chirag jayswal
Importance of Microbes Spoil foods Make / flavor foods Petroleum & Coal: unrecycled remnants Decay wooden structures Corrode iron & steel, damage concrete Food source Allow fouling community establishment chirag jayswal
Classification of Microbes Plant vs Animal cell Cell Wall Chloroplasts Cell Nucleus Organelles/ Vacuoles Cytoplasm Cell Membrane chirag jayswal
Classification of Microbes Prokaryotic vs Eukaryotic Nuclear Membrane chirag jayswal
Classification of Microbes Prokaryotic Domain Archaea Domain Bacteria Domains and Kingdoms Eukaryotic Domain Eukarya –Protista –Fungi –Plantae –Animalia chirag jayswal
