- 1name the 3 types of light microscopydark field
phase contrast
fluroesence - 2describe dark field microscopybright image dark background
living organisms without staining
shows eurkry. internal structure
identifies bacteria - 3describe phase contract microscopyinhances contract between intercellular structures
observe living cells - endospores - 4describe fluroesence microscopystained with flurochrome
- 5state 4 preparation methodsthin specimens -TEM
chemically fixed/stained
shadowing
freeze etching - 6what does shadowing doattaches thin layer of heavy metal
- 7what does freeze etching dofreeze along membrane
- 8describe transmission electron microscopyelectrons that aren't scattered produce image
more scattering - darker image
specimen needs to be thin - 9describe scanning electron microscopyproduces 3d image
- 10name 3 other less popular microscopy methods, what can they observescanning tunnel
automatic force
have very high resolution can observe individual atoms
