Answer;
-Electron microscopes can not view live cells because the method of preparation is lethal.
Explanation;
-The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
-There are many different disadvantages to using a electron microscope for example they are extremely expensive which limits the availability to use them. Furthermore researchers are unable to observe the image in color, as electrons do not possess color, which may not allow the image to be understood easily.
-Additionally the use of the electron microscopes require a large space for example a whole room which may not be feasible.
