Archea and Eubacteria
• Archea KingdomAll prokaryotic single celled organisms. No Peptidoglycan in cell wall Most ancient and extremeThey live in the harshest environmentsMethanogens (anaerobic),
thermoacidophiles (hot) and halophiles (salty)
• Eubacteria KingdomTrue bacteria, all prokaryotic single celledHave Peptidoglycan in cell wallClassified by their shape and gram staining
Shapes and Examples
• Sphere- Cocci, can occur in chains Streptococcus Pneumoniae which can cause strep throat or Scarlet fever, or grapelike clusters Staphylococcus aureus which can cause skin infections and Toxic Shock syndrome
• Rod- Bacillus ex Escherichia coli (E.coli), Lactobacilli which can cause tooth decay or one strain makes Sourdough bread, other bacilli can cause botulism, typhoid fever, and anthrax
• Spiral- Spirilla comes in 3 shapes 1. Vibro which is curved caused Cholera, 2. Spirillum (thick spiral), and 3. Spirochete (thin spiral) ex. Treponema pallidum causes Syphilis and another strain can cause Lyme disease
Essential Bacteria: ecosystems depend on these small organisms
• Cyanobacteria- photosynthetic/producers, building blocks of most aquatic food webs
• Nitrogen- Fixing Bacteria- symbiotic relationship with plants, they help them absorb nitrogen from the soil.
• All Eukaryotic, multicellular, heterotrophs (saprotrophs or detrivores living off dead and decaying organisms or decomposers), cell wall made of chitin (type of protein), and classified by reproductive structures.
• Mycoses is the term for Fungal Infection, Fungus destroys the cells around the infection site, to fight fungal infection you have to destroy the cell wall
• Fungi are important part of an ecosystem because they recycle nutrients/ decomposers
Classifications of Fungi • Club Fungi – Basidiomycota , Basidia, ex Mushrooms• Sac Fungi- Ascomycota, Asci, ex. Truffles,
