because somone put them on
Electron micrographs are typically in black-and-white because electron microscopes use electrons to produce images, which do not have color. The electrons interact with the specimen to create contrast, resulting in a grayscale image. Although false color can be added to highlight different structures, the base image is still in black-and-white.
An electron microscope can magnify up to more than 1015 times. It is always in black and white but INSANELY detailed. It is black and white because electrons are negative(ELECTRON microscope).
The speciman you are viewing must be in a vacuum, and be coated with a metal film, therefore the specimen can't be alive and if its a Transmission Microscope- Speciman must be extrememly thin so that the electrons can pass through them. The image is black and white.
every think but black and white tv
People tend to remember things better in color because it adds more visual detail and realism to the memory. Colorful images are often more vivid and engaging, which can lead to stronger and more accurate recollection compared to black and white images.
A microscope that shows black and white images is called a monocular microscope. It typically uses a single eyepiece and objective lens to magnify and view samples in grayscale.
This picture was likely taken with a scanning electron microscope (SEM). SEM uses a focused beam of electrons to create detailed images of the surface features of a specimen, producing high-resolution black and white images.
Images produced from a transmission electron microscope have high resolution, allowing for detailed visualization of internal cellular structures. They have a black and white appearance due to the interaction of electrons with the sample. These images provide information on the morphology, internal structure, and composition of the specimen.
Because it uses electrons instead of light, and light is required for color to be present.
It is black and white.
real answer is A+ Decoder tubes for color or black and white images
You would use an electron microscope to view a Golgi apparatus.
Electron micrographs are typically in black-and-white because electron microscopes use electrons to produce images, which do not have color.

Although false color can be added to highlight different structures, the base image is still in black-and-white.
Use of EM (electron microscope), because of the their high resolution power. In order to visualize Virus under EM they are either coated or stained with platinum or osmium (heavy metal) in such a way that the protein structure of the Virus is not destroyed. The particles are observed by passing electron through specimen and observing it in fluorescent screen. Area where electrons don't pass become black due to havy metal but are printed white because images are photographed in negative.

Aphrodite is Black ! but on GOOGLE IMAGES it shows her white.
because it needs the black and white to see what is under it !
