Bacteria:
Classification and Structure
![Page 2: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/2.jpg)
What are the 6 Kingdoms?
• Archaebacteria• Eubacteria• Protists• Fungi• Plants• Animals
![Page 3: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/3.jpg)
Bacteria are prokaryotes
• Pro – before• Karyon – nucleus• The simplest forms of life are
prokaryotes.• Earth’s first cells were
prokaryotes.
![Page 4: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/4.jpg)
Lots of Them!
• Prokaryotes are Earth’s most abundant life forms.
• They can survive in many environments.
• They can get energy from many different sources.

Prokaryote Review
• Mostly single-celled• No nucleus or organelles• Circular chromosomes• Cell walls• Reproduce mostly asexually• Anaerobic or aerobic• Heterotrophic or autotrophic
![Page 6: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/6.jpg)
We are looking at the first two
• Archaebacteria• Eubacteria
![Page 7: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/7.jpg)
Classification of Bacteria
• Archaebacteria: extremists• Eubacteria:
–Heterotrophs–Photosynthetic autotrophs–Chemosynthetic autotrophs
![Page 8: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/8.jpg)
Archaebacteria
• Methane producers – anaerobic• Halophiles
–Halo = salt–Philia = love
• Thermophiles–Thermo = heat
![Page 9: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/9.jpg)
Archaebacteria
• Live in extreme locations:–Oxygen-free
environments–Concentrated
salt-water–Hot, acidic
water
![Page 10: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/10.jpg)
Eubacteria• Parasitic heterotrophs (Streptococcus)• Saprophages
–Sapro = death–Phage = eat
• Cyanobacteria (blue-green algae)–Photosynthetic
• Chemosynthetic autotrophs (Rhizobium)
![Page 11: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/11.jpg)
Eubacteria - Heterotrophs
• Found everywhere• Parasites: live off of other
organisms• Saprobes: live off of dead
organisms or waste (recyclers)
![Page 12: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/12.jpg)
Eubacteria: Photosynthetic Autotrophs
• Photosynthetic: make their own food from light
• Cyanobacteria: blue-green, yellow, or red
• ponds, streams, moist areas
![Page 13: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/13.jpg)
Eubacteria: Chemosynthetic Autotrophs
• Get energy by breaking down inorganic substances like sulfur and nitrogen
• Make nitrogen in the air usable for plants {Very Important}
![Page 14: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/14.jpg)
Structure of Bacteria
• Two parts to Bacteria Structure:–Arrangement–Shape
![Page 15: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/15.jpg)
Arrangement
• Paired: diplo• Grape-like clusters: staphylo• Chains: strepto
![Page 16: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/16.jpg)
Bacteria are Named by Shape
• Cocci (ball-shaped)–Streptococcus mutans
• Bacillus (rod-shaped)–Clostridium botulinum
• Spirilli (spiral-shaped)–Treponema palladium
![Page 17: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/17.jpg)
Shape
• Rod: bacillus• Spheres: coccus• Spirals: spirillum
![Page 18: Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.](https://reader030.fdocuments.in/reader030/viewer/2022033019/56649ee15503460f94bf247d/html5/thumbnails/18.jpg)
Examples
• Streptococcus: chains of spheres• Staphylospirillum: Grapelike
clusters of spirals• Streptobacillus: Chains of rods

Germ Theory of Disease
• Joseph Lister – Aseptic Techniques
• Robert Koch – Germ Theory–A specific microorganism causes
a specific disease
