Scanning Electron Microscopes have a much larger zoom range. therefore the image from a SEM is more in depth. think of it as looking at a basketball from far away... you see an orange ball. but when you look at it upclose, you see the black lines and dimples on the ball. same goes for whatever your looking at under the SEM
a TEM microscope privides an detailed image of the inside of a specimen a SEM microscope provides a 3D image of a specimen take for exampel a sperm in a TEM microscope you would see the inner stucture of the sperm in a SEM microscope you would se in detail the exact form shape of the sperm
No it doesn't , but you can make 3d image by taking three or four 2D scans of titled sample and then using image processing reconstruct it in 3-D

1.SEM samples require minimal preparation 2 Data is generated in digital form 3 SEM is easy to operate and user friendly 4 It produces image in 3-dimension which gives precise information about the specimen
