TEM images only have a view of the inner structure and are black and white so scientists don't actually know the colour of cells.
SEM images are essentially a magnifies view of the specimens outer structure and are also black and white.
Though both images can be contrasted via computers to add colour to see images more clearly

What type of microscope can produce three - dmensional images of a cell's surface?
Scanning Electron Microscope (SEM)
What does the SEM microscope use to magnify images?
The SEM microscope uses a high-energy beam of electrons that interact with the atoms that make up the sample producing signals that contain information about the sample's surface topography, composition and other properties such as electrical conductivity.
What Microscope that gives 3-D image?
There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
What disadvantages do SEM microscopes have of light?
The two main advantages of SEM over light microscopy is that the SEM has a much deeper depth of field and that it has higher resolution than a light microscope can achieve and the resultant much higher magnification from the SEM.
What is the mathematical relationship between LM and TM and SEM?
the relationship between the LM, EM, SEM is the limit of resolution
How do electrons microscopes differ TEM vs. SEM?
TEM gives 2D images and SEM gives 3D images.
What type of microscope can produce three - dmensional images of a cell's surface?
Scanning Electron Microscope (SEM)
Why are sem images black and white?
because it needs the black and white to see what is under it !
How do sem and tem produce images?
SEM, which stands for Scanning Electron Microscope produces images by penetrating the specimen with a fixated beam. This beam is used to scan a rectangular portion of the specimen. Images are reliant on surface processes and they are incomplete, unlike TEM images. TEM, which stands for Transmission Electron Microscope utilizes an electron emission of high voltage. They produce complete images.
How does the image you see in a SEM differ from a light microscope?
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
What is 'Sempre sempre' when translated from Italian and Portuguese to English?
"Always, always!" is an English equivalent of the Italian and Portuguese phrase Sempre, sempre! The adverb serves the same function in both Romance languages. The respective pronunciations nevertheless will differ since Italians pronounce the word as "SEM-prey" and Cariocan Brazilians and continental Portuguese say "SEM-pree."
What is the difference between standard error of mean and standard deviation of means?
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
What does the SEM microscope use to magnify images?
The SEM microscope uses a high-energy beam of electrons that interact with the atoms that make up the sample producing signals that contain information about the sample's surface topography, composition and other properties such as electrical conductivity.
