Why the images revealed by electron microscopy might not accurately represent structures in living cells?

Because electron microcopy images are not taken 'in situ'. In other words, to capture an image using an electron microcope, the cells are often heavily treated in order to allow the image to be be generated. These treatments include freezing, fracturing and/or coating with heavy metals. Such treatments kill the cells, and therefore we aren't capturing an image of a living cell, but a cell we have killed and treated. Because these treatments are not encountered in the 'normal day-to-day life' of the living cells, we can't say for sure that they don't affect the structure of the cell we're trying to take the picture of.

Does light microscopy offer better magnification than electron microscopy?
No
Which type of microscopy is used for colorless specimens?
Transmission electron microscopy
What type of microscopy does not use light?
Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.

Light microscopy and electron microscopy differences in practical use?
Electron microscopy gives higher resolution, but it's expensive, slow, and cumbersome. And for many things, it's not needed.
Which type of microscopy is useful for viewing colorless specimens?
Transmission electron microscopy
Construction and working of transmission electron microscope?
transmission electron microscopy
If Electrons pass through thin slices of cells or tissues and produce flat two dimensional images in electron microscopy?
Transmission electron microscopy
