Lecture 2 Flashcards
Observing microorganisms through a microscope
What type of light does fluorescence use
UV light
Absorb UV light and emit visible light
Florescence microscopy
Popularly used as a tag to illuminate living cells in fluorescent microscopy
GFP ( Green fluorescent protein)
Microscopy that contains cells with fluorochrome dyes, short wavelength (blue light) used to excite dyes
confocal microscopy
True/ False- confocal microscopy is expensive
True
Uses electrons instead of light
Electron microscopy
True\ False Viruses are too small to be seen by a light microscope
true
Specimens may be stained with heavy metal salts
TEM (Transmission electron microscopy)
Ultra thin sections of specimens. Light passes through specimen, then an electromagnetic lens, to a screen or film.
