This Concept Map, created with IHMC CmapTools, has information related to: anas,zul,man,fir, KINGDOM MONERA ???? importances of bacteria, classfication of bacteria E. coli 1. Cannot tolerate with extreme environment 2. Peptidoglycan is present in cell wall 3. Lipid structure in plasma membrane: -straight-chain fatty acids bonded to glycerol by ester linkage 4. DNA is not wrap by round histone protein, importances of bacteria ???? Prokaryote in the research and technology *Used to digest organic wastes,chemical products,make vitamins & antibiotics *Used in genetic engineering *As a biological agent - Bacillus thuringiensis to attack insects, unique characteristics of bacteria ???? Reproduction *by binary fission *by endospore formation (only if the condition is not suitable), unique characteristics of bacteria ???? Prokaryote *without nucleus and unicellular, importances of bacteria ???? Symbiotic prokaryotes * Mutualistic bacteria : E.Coli sp. - live in the intestine - benefits from undigested material - release vitamin K and B12 produce blood component) -digest cellulose in cows and goats stomach * Commensalistic bacteria -live in/on organism of others species and cause no harm, unique characteristics of bacteria ???? Flagella *many bacteria are motile because of flagella that help for movement and ability, unique characteristics of bacteria ???? Cytoplasm *contain chromosome and plasmid *lack membrane enclosed organelles (mitochondria & endoplasmic reticulum), importances of bacteria ???? Recycling of chemical elements in ecosystem (nitrogen fixation) * Bacteria lives in nodules on the root of of legumes Eg : beans,peas,clover -convert nitrogen to ammonia(a form of nitrogen used by plants), KINGDOM MONERA ???? unique characteristics of bacteria, KINGDOM MONERA ???? classfication of bacteria, unique characteristics of bacteria ???? Cell wall *made up of peptidoglycan *some species produce capsule - provide protection against phagocytosis and attach to surface *have Pili - help bacteria to adhere to one another or attah to certain surface (Sex Pili is important in transmitting DNA between bacteria), classfication of bacteria sulfolobus 1. Can tolerate or adapted to extreme environment 2. Peptidoglycan is not present in cell wall 3. Lipid structure in plasma membrane: -branched-chain hydrocarbons linked to glycerol by other linkage 4. DNA is wrap with round histone protein, unique characteristics of bacteria ???? Have a circular DNA molecule *generally have a single chromosome (circular DNA) *without histone protein *most bacteria have plasmid(smaller circular fragment of DNA), unique characteristics of bacteria ???? Mesosome *an invagination of the palsma membrane to form a simple membranous structure
