Types of Microbes Bacteria (pl.)/ Bacterium (s.) unicellular prokaryote (prokaryote (pro=first; kary=nut, nucleus) – genetic material not enclosed in a special nuclear membrane) appear in several shapes, most common are: o bacillus – rod-like o coccus – spherical or ovoid o spiral – corkscrew or curved some can also appear star-shaped or square-shaped may form in singles, pairs, chains, clusters, or other formations characteristic to a genus or species enclosed in cell walls composed of carbohydrate and protein complexes called peptidoglycans reproduce by cell division (binary fission) much like mitosis nutrition: varies by genus and species o organic chemicals derived from dead or living organisms o photoautotroph - photosynthesis o chemoautotroph – inorganic chemical nutrition movement - some swim by flagella Archea / archeabacteria unicellular prokaryote cell walls lack peptidoglycan usually live in extreme environments three main groups: o methanogens –produce methane as a waste production of respiration

Unformatted text preview: o halophiles – live in extremely salty environments (Great Salt Lake or Dead Sea) o thermophiles – live in hot sulfurous water (hot springs, deep sea vents)-not known to cause disease in humans Fungi (pl.) / fungus (s.) eukaryotes, unicellular or multicellular (eu=true) eukaryotes=genetic material is enclosed in a nuclear membrane cell walls composed of chitin (carbohydrate-based) yeast – unicellular form, oval in shape, larger than bacteria molds – multicellular form, form visible masses called mycelia o mycelia composed of long filament (hyphae) that branch and intertwine o appear as a cottony growth on bread and fruit mushrooms –larger multicellular fungi that resemble plants reproduction is sexual or asexual (sexual=two parents; asexual = one parent) nutrition – absorb solutions of organic material from environment (soil, seawater, freshwater, plant host, animal host) slime molds- characteristics of both fungi and amoeba (protozoan)...
