whats the definition for magnification
how many times bigger the image is than the object
definition for resolution
minimum distance that 2 objects are apart to appear as seperate objects
what are the pros and cons of a light microscope
uses light
can view live specimens
uses glass lenses
can see colour
cant see organelles
low mag
pros and cons of electron microscope
uses magnets
no colour
complex slide prep
only view dead specimens
greater resolution
observe smaller organelles
needs thinner specimens
electron microscopes have
higher resolution
shorter wavelength
distinguish objects closer together
see internal structures of organelles
