Question

Quizplus · Accepted Answer

The transmission electron microscope (TEM) is the best choice when biologists wish to study the internal ultrastructure of cells with the finest resolution. The TEM uses a beam of electrons that pass through a thin specimen, allowing for high magnification and resolution of internal structures. The other options - phase-contrast light microscope, scanning electron microscope, and confocal fluorescence microscope - are also useful for studying cells, but they do not have the same level of resolution as the TEM when it comes to studying internal structures.
