Document Summary
Microscope anatomy (top right to bottom: ocular lense, nose piece, objective lens. Scanning lens (4x: stage, condenser: light reflects through objective lens. Iris diagram: controls the light: base: bottom of the microscope (bottom left to up, body/arm, focusing knob: shifts so you can see slides better microscope terms: Total magnification: combination of ocular magnification x objective magnification x body mag- nification. Working distance: distance between objective lens and side when its in focus parfocal: swapping from one lens to another without focusing. Prokaryotes (eubacteria and archeae: shapes coccus : spherical organism (ping pong shaped) Pairs: ex. diplococci, neisseria (causes meningitis and gonnoreah); on one plane. Single and pairs are both too common to be used for good tool ids, but the rest are good bacilli. 8 cube: sarcinae; ex. sponosarcin: two planes. Single: rod shaped organism; cylindrical; common; not a good id. Pairs: diplobacilli; common; not a good id. Chains: streptobacilli; common; not a good id.
