In order to see the image better scientists will treat slides with dye and use video cameras and computer processors to observe movements.

Cells are coated with metal (gold).
The electron beam bounces off the object and is read by a detector.

Below are five different images of the same mosquito.
The SEM shows very detailed 3-dimensional images at much higher magnifications .

Cells are sliced extremely thin which allow electrons to pass through the object to produce an image.

bacteria
Golgi apparatus
Blood (platelet) ?????????????

Light microscopes allow scientists to view living cells and
They are MUCH cheaper than the SEM and TEM.
SEM and TEM can view extremely small objects, can make objects millions of times their original size but can’t view living cells.
