Document Summary
8:40 am: how microbes shape and change our lives, too small to be seen, prokaryotes, cells and organelles evolved from this, bacteria round (coccus shaped, unicellular, rod (bacillus, no nuclear membrane. Spiral: enclosed in cell wall made of carbs and protein called peptidoglycan, photosynthesis, motile. Flagella: binary fission, archaea, do not cause disease, no peptidoglycan cell walls, very extreme conditions, extreme halophiles. Salt: extreme thermophiles, temp, methanogens, make methane as waste, eukaryotes microorganisms. Fungi: multi or unicellular, do not do photosynthesis, made of chitin cell walls, oval microbes (yeast) or like mushrooms, molds are most common, mycelia masses, absorb organic material from environment, protozoa. Found on bread or food or as plant like in forests: unicellular, use flagella and pseudopods to move, gain nutrients through special structures. Free entities or parasites: algae, multi or uni cellular. Live in water: photosynthesis, cellulose cell walls. Freshwater, saltwater, soil, plants (?: viruses, need electron microscope, not cellular, na core with protein coat.
