9
Eubacteria Prokaryotic, single celled Heterotrophic or autotrophic Reproduce asexually with binary fission
10
Eubacteria 1 circular chromosome and a secondary plasmid
11
Eubacteria Classified based on shape, spores, metabolism(glycolysis for anaerobes, cellular respiration for aerobes), and ability to “gram stain”
14
Eubacteria
15
Cyanobacteria (pond Scum) Oscillatoria princeps D-Eubacteria K-Eubacteria P-Cyanobacteria C- Cyanophyceae O- Oscillatoriales F- Oscillatoria G- Oscillatoria S- O. princeps
16
Protista Protista are simple, usually unicellular eukaryotic organisms. Not animals, not plants, not fungi = Protist!! Usually aquatic Aerobic Very important component of plankton Reproduce sexually or asexually Divisions (phyla) classified based on Animal like, Plant like or Fungus like
17
Protista Animal like-> “Protozoa” – Rhizopoda – Apicomplexia – Zoomastigophora – Ciliophora
18
Protista Division Rhizopoda Move with a pseudopod (false foot) Eat by engulphing food (phagacytosis)
19
Protista Division Zoomastigophora “Zooflagelates”
20
Protista Division Ciliophora example- Paramecium Use cilia to move around
21
Protista Plantlike Protista-> “Algae” contain chlorophyll and carry out photosynthesis Very important aquatic primary producers – Dinoflagellata – Euglenophyta – Bacillariophyta – Chlorophyta – Phaeophyta – Rhodophyta
22
Protista Bacillariophyta The “diatoms”
23
Protista Dinoflagellata “Dinoflagelates” Sometimes show biolluminescence Red Tide
24
Protista Euglenophyta – Unicellular flagellates – Primarily freshwater, but important in some marine environments – Many are heterotrophic (saprotrophic or phagocytic)
25
Protista Chlorophyta Green algae
26
Protista Phenophyta Brown Algae Alt of Generations
27
Protista Rhodophyta Red Algae Nori- Iodine source
28
Protista Fungus like Myxomycota- slime molds Many nuclei for each giant cell full of cytoplasm Use pseudopodia The organisms in this group have a complex life cycle during the course of which they go through unicellular, multicellular, funguslike (form spores) and protozoanlike (amoeboid) stages.
30
Protista Oomycota Water molds Some species (e.g., Saprolegnia, Achyla) are parasites of fishes and can be a serious problem in fish hatcheries. Downy mildews damage grapes and other crops. Phytophthora infestans, the cause of the "late blight" of potatoes. In 1845 and again in 1846, it was responsible for the almost total destruction of the potato crop in Ireland. This led to the great Irish famine of 1845–1860. During this period, approximately 1 million people starved to death and many more emigrated to the New World. By the end of the period, death and emigration had reduced the population of Ireland from 9 million to 4 million. Phytophthora ramorum, which is currently killing several species of oaks in California. Cell wall of cellulose, like plants
32
Fungi Eukaryotic, nonvascular, Heterotrophic, reproduce sexually and asexually with spores Alternation of generations N-2N Most are multicellular Cell walls made of Chitin Decomposers, parasites, or mutualists (Mycorrhizea on plant roots for N)
33
Fungi Exoenzymes- digest food externally, then ingest it Store food energy as glycogen, like animals Vegetative-> Hyphae- Mycellium Fruiting body-> Produces spores (the cap)
35
Fungi Phyla (based on spore arrangement) Chytridiomycota Zygomycota Asomycota Basiomycota
36
FUNGI Chytridiomycota (primitive Fungi) Sexual and asexual reproduction Spores are motile with a flagella
37
FUNGI Zygomycota (the molds) Sexual reproduction with spores with very thick walls
38
FUNGI
39
Ascomycota - Sac Fungi -75 % of all fungi species -Sexual reproduction -Spores can be found in an ascus sac -Yeasts, Penicillium, truffels
41
FUNGI Basidiomycota - “da club fungi” -sexual spores are born externally on a club shaped basidium -Gills on fruiting body to increase surface area
42
Basidium
44
Pizza Mushroom D- Eukarya K- Fungi P- Basiomycota C- Hymenomycetes O- Agricales F- Agricaceae G- Agaricus S- A. Bispores
