Document Summary

The study of small microscopic organisms: bacteria archaea protists algae fungi viruses. Have organelles: ribosome, cytoplasmic membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, mitochondria. Multiple, linear chromosomes, single genes, no sigma factors. No cell wall in animal cells, chitin/cellulose wall in plants/fungi. Limilted metabolism & tolerance to extreme enviro. Nucleoid: no membrane around it(also archaea has this) Circular and singular chromosome, operons of genes, sigma factors. Consume: sugar, light, toxins(h2s), make alcohol, breath uranium, etc * diverse metabolism. Grow: can grow in some extreme conditions(hot springs 80c, arctic ocean4c, strong acid, high in atmosphere, deep in earth) Bacteria + animal(tube worm) bacteria + plant(root nodules) bacteria + fungi(lichens) bacteria+bacteria(biofilms: know the 4 different requirements for microscopy* Resolution: ability to distinguish 2 points that are close together. 1572-1633: cornelius drebbel: inventor, alchemist, designed early telescope. 1620 voynich manuscript: 100 pages of drawings in unknown language, maybe 1st microbio textbook.
