Document Summary
Organisms that are too small to be seen with the unaided eyes. Need microscope to see them: typically 0. 2mm or smaller, few are pathogenic. Producers (can do photosynthesis & provide nutrients for other organisms) and / 0r decomposes (breakdown dead material) in the ecosystem. Biological production by pharmaceuticals: insulin, clotting factors, inf, etc. (isolate gene from organism & put into bacteria to produce lots and lots of pure copies for use, knowledge of micro organisms allows us to: Prevent diseases from transmission (helped us improve our healthcare) Conduct medical procedures without infections (thanks to antibiotics and sterile techniques: development of aseptic techniques. Sterile = nothing will grow sterile aseptic. Basically are what seeds are to plants. Can be unicellular (yeast) or multicellular (mold & mushrooms: protozoa. Absorb or ingest organic chemicals for energy. Can feed themselves, but they can also become food for the rest of the food chain: multicellular animal parasites (are microscopic in larval stage)
