This Concept Map, created with IHMC CmapTools, has information related to: 11.2_Wan Nabilah, cannot tolerate extreme environment ???? peptidoglycan is present in cell wall, DNA is wrap around histone protein ???? eg,Sulfolobus, UNIQUE CHARACTERISTICSS ???? pili help to adhere to another or attach to certain surface, DIVERSITY BACTERIA ???? cell shapes, Position of flagella ???? Lophotricsous -two or more flagella at one pole of the cell, DNA is wrap around histone protein ???? eg.E,coli, Cyanobacteria, CLASSIFICATION BACTERIA ???? Archaebacteria (Sulfolobus), Position of flagella ???? Monotrichous -a single polar flagellum, adapted to extreme environment ???? peptidoglycan not pesent in cell wall, Position of flagella ???? Peritrichous -flagella distributed over the entire cell, IMPORTANCE OF BACTERIA ???? Phatogenic bacteria -some bacteria are pathogenic -Neisseria gonorrhoeae the causative agent of the sexually transmitted disease gonorrhoea -other disease caused by bacteria a)cholera(taun)-Vibrio cholera (from human faeces) b)food poisoning-Salmonella sp., Symbiotic prokaryote ???? Mutualistic bacteria -E.coli live in intestines of humans benefit from undigested material & released vitamins K & B 12 -use to produce blood component -in stomach cows & goats mutualistic bacteria digest cellulose, type of nutrition ???? producer, UNIQUE CHARACTERISTICSS ???? simple uncellular, Archaebacteria (Sulfolobus) ???? adapted to extreme environment, UNIQUE CHARACTERISTICSS ???? Prokaryote, have circular DNA ???? most bacteria also have ( circular fragment dna), cell shapes ???? Spiral single-spirilium, Prokaryote ???? no nucleus, UNIQUE CHARACTERISTICSS ???? reproduce by binary fission
