1 Archea and Eubacteria Archea Kingdom Eubacteria Kingdom All prokaryotic single celled organisms.No Peptidoglycan in cell wallMost 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
2 Shapes and ExamplesSphere- 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 syndromeRod- 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 anthraxSpiral- 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
3 Essential Bacteria: ecosystems depend on these small organisms Cyanobacteria- photosynthetic/producers, building blocks of most aquatic food websNitrogen- Fixing Bacteria- symbiotic relationship with plants, they help them absorb nitrogen from the soil.Helpful: fermentation, digestion, biotechnology, nitrogen fixing, decomposers, oxygen producersAntibiotics kill bacteria by destroying the cell wall, gram negative have an extra lipid layer that prevents the antibiotics from entering the cell.
4 Review of Bacteria All bacteria: Some Bacteria: Reproduce asexually Single celledHave cell wallSingle strand of DNASome Bacteria:AutotrophicHeterotrophicSome move by flagella, slime, spiral motionSome produce endospores which allow them to go dormant during hostile conditionsSome produce toxins
5 Kingdom Protista Kingdom of Mostly single celled organisms Categorized by their likeness to 3 other kingdomsAll Eukaryotic some Autotrophic and some Heterotrophic
6 Algae- Plant like Protist Algae or Plant-like, Autotrophic, classified by pigment with no cell wall, come form elaborate colonies and multicellular structures (kelp and seaweed)Chrysophyta- Golden Algae ex diatomsPyrrophyta- bioluminescent/glowex. DinoflagellatesEuglenaphyta- ex EuglenaRhodophyta- redPhaeophyta- brown, seaweed and kelpChlorophyta- green, ex Volvox, Spirogyra

8 Protozoa or Animal like Protist Protozoa or Animal-like, classified by mode of movementSarcodina ex. Amoeba- move by pseudopodia “false foot”Ciliophora ex Paramecium- move by cilia, tiny hairsZoomastigina ex Trypanosoma (African Sleeping Sickness) moves by flagellaSporozoa, are the parasitic animal like protista, include Plasmodium which causes Malaria
10 Fungus-like ProtistaFungus-like are all Heterotrophic with no cell wall, absorbing nutrients directly through cell membraneInclude Plasmodium or Slime Molds and Downy Mildews
11 Kingdom FungiAll 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 wallFungi are important part of an ecosystem because they recycle nutrients/ decomposers
12 Classifications of Fungi Club Fungi – Basidiomycota , Basidia, ex MushroomsSac Fungi- Ascomycota, Asci, ex. Truffles, Morels,Yeast, and Athletes Foot FungusZygote Fungi – Zygomycota, Sporangia, ex. Bread moldsImperfect- Deuteromycota, reproduce asexually, ex PenicillianLichen- Mycophycophyta, symbiotic relationship between fungus and photosynthetic cells of cyanobacteria or algae.
