cells and microscopy Flashcards
what are cells
are the basic units of life
what do microscopes do?
they magnify images is then its easier to see cells and their structures more clearly
how do you calculate magnification
magnification= image size/ actual size
why does the material being used on the slide have to be thin
so then light or an electric beam can pass through it
why is a coverslip needed
in order to protect the specimen/ the lens if they should touch
what do stains help to do
distinguish different features in the specimen
for an electron microscope why are the better than light microscopes
as they have a greater magnification
disadvantage of an electron microscope
can only examine dead material with an electron microscope
what is the equation for total magnification in a LIGHT microscope
total magnification= magnification of eyepiece lens x magnification of objective lens
name all 6 features on a light microscope
eyepiece lens, coarse focus, fine focus, objective lens , stage, light source
