1 of 5
Why may an electron microscope be choosen over using a light microscope?
elecron=better resolution and magnification, shoter wavelength- see organelles but cant use living specimen
2 of 5
Explain how TEM's and SEM's work and their pros and cons
TEM-transmitt beam of electrons, dender parts adsorb more so darker, pro-high res, con-non-living/thin SEM-scan beam, knock off electrons, cathode ray, pro-3d, not thin, con-lower res than TEM, non-living

How do you get from a smaller unit to bigger and visa versa?
smaller-bigger= 1000, bigger-smaller= x 1000
