light microscope

Question 4

fluorescence microscopy

Answer 4

fluorescent substances attached to specific molecules in tissue glow differently colour when subjected to ultraviolet light

Question 5

Electron microscopes

Answer 5

objects illuminated with a beam of electrons rather than light.
up to 1.5 x 10^6

Question 6

TEM microscopes

Answer 6

transmission electron microscope
allows viewing of internal structures

Question 7

SEM microscopes

Answer 7

scanning electron microscope
can render tiny details but only on surface of ibject

Question 8

confocal laser scanning microscope

Answer 8

makes possible to study (living) specimens too thick to be used using compound microscope.
2D images taken, make slices

Question 9

scanning tunneling microscope

Answer 9

more magnifying power than electron microscope (2.0 x 10^8)
allows for 3D mapping of surfaces like DNA
