Kingdom: # of cells in one bacteria: ____________-(They are single celled organisms) Type of Cells: ___________________________ (“Simple Cells”) Genetic Material: _______is found floating in the cytoplasm-no nucleus Structure: ALL BACTERIA ARE ONE OF THREE BASIC SHAPES_____ Round: _______________ Rod Shaped: ___________ Spiral: _______________ Reproduction: _________________________________________ by binary fission: (when a bacteria divides in half, producing two identical daughter cells) Bacteria can, however, exchange some of their DNA through ________________ (when DNA is shared between the pillus of two bacteria) Nourishment: Not all bacteria are alike! _______________________-take in food from other sources. _______________________-can make their own food. Some bacteria do this through photosynthesis (using light) and some do this through chemosynthesis (using chemicals). Respiration (Releasing Energy): Not all bacteria are alike! Obligate aerobes: must use __________________________________ Obligate anaerobes: must live without _________________________ Facultative anaerobes: can survive with OR without ______________ Locomotion: Not all bacteria are alike! Some do _______________________________. Some use their __________________________. Some can snake or ________________ forward. Some glide on layer of____________________. Other: Bacteria can turn themselves into ____________ (mummified bacteria) when the conditions around them get rough. When more water or food becomes available, they can “come back” to life again! Some bacteria can stay spores for years! Helpful Examples: Producers-capture energy from the sun during photosynthesis. They are at the start of many food chains! Decomposers-break down nutrients in dead matter. They help recycle nutrients! Nitrogen fixation-bacteria take nitrogen gas in the air and change it into a useable form. ALL OTHER living things rely on bacteria to do this for them. Without these bacteria, everything would die! Human uses-bacteria are used by us to make things we need. Digest Oil Remove poisons from water Make drugs like Antibiotics & Insulin Oli live in our intestines and help us break down food and make vitamins for us Harmful Examples: CALLED PATHOGENS-VERY FEW BACTERIA ARE HARMFUL! Break down cells and use them for food Myobacterium tuberculosis-destroys lung tissue Salmonella typhimurium-destroy cells in the intestine Releasing Toxins (wastes that are harmful) Strep Throat: Stretococcus pyogenes Diptheria: Corynebacterium diptheriae Tetanus: Clostridium tetani Tooth Decay: Streprococcus mutans Other Diseases Caused by Bacteria Disease Causative agent Leprosy (Hansen's Disease) Mycobacterium leprae Whooping Cough Bordetella pertussis Typhoid Fever Salmonella typhi Cholera Vibrio cholorae Plague Yersinia pestis Meningitis Neisseria meningitidis Anthrax Bacillus anthracis Botulism Clostridium botulinum Bacterial Dysentry Shigella dysenteriae Diarrhoea Escherichia coli Gas Gangrene Clostridium perfringens Syphilis Treponema pallidum Gonorrhoea Neisseria gonorrhoeae Trench Fever Rochalimaea quintana Typhus Fever Reckettsia prowazekii Lyme Disease Borrelia burgdorferi Toxic Shock Syndrome Staphylococcus aureus Rocky Mountain Spotted Fever Rickettsii riskettsii Legionnaires' Disease Legionella pneumophilia Gasteroenteritis Campylobacter spp. Helicobacter pylori Kingdom: Eubacteria & Archaebacteria # of cells in one bacteria: One-(They are single celled organisms) Type of Cells: Prokaryotic (“Simple Cells”) Genetic Material: DNA is found floating in the cytoplasm-no nucleus Structure: ALL BACTERIA ARE ONE OF THREE BASIC SHAPES Round: Cocci Rod Shaped: Bacilli Spiral: Spirilla Reproduction: Assexual Reproduction by Binary fission: (when a bacteria divides in half, producing two identical daughter cells) Bacteria can, however, exchange some of their DNA through conjugation. (when DNA is shared between the pillus of two bacteria) Nourishment: Not all bacteria are alike! Heterotrophs-take in food from other sources. Autotrophs-can make their own food. Some bacteria do this through photosynthesis (using light) and some do this through chemosynthesis (using chemicals). Respiration (Releasing Energy): Not all bacteria are alike! Obligate aerobes: must use oxygen Obligate anaerobes: must live without oxygen Facultative anaerobes: can survive with OR without oxygen Locomotion: Not all bacteria are alike! Some do not move. Some use their flagella. Some can snake or spiral forward. Some glide on layer of slime. Other: Bacteria can turn themselves into spores (mummified bacteria) when the conditions around them get rough. When more water or food becomes available, they can “come back” to life again!
