Features of a light microscope
Transmitted through a specimen
Lower magnifcation and resolution
uses rays of light
observe alive and dead
images in colour
thin specimens
Features of Transmission electron microscope
only really thin specimens
black/white image
electrons are transmitted through specimen
beams of electrons
high resolution
only observe dead specimens
larger magnification
Define resolution
minimum distance between and objects before they appear as one
Define magnification
how many times larger an image is
