Transmission and scanning electron microscopy differ because transmission electron microscopy shows two-dimensional ultrastructure, while the scanning electron microscopy shows three-dimensional structure. transmission electron microscopy has high resolution, but scanning electron microscopy does not. transmission electron microscopy shows contrast, but scanning electron microscopy does not. transmission electron microscopy uses light as an illumination source, while scanning electron microscopy uses electron beams as an illumination source. transmission electron microscopy has much higher magnification than scanning electron microscopy.

True or false : each objective of a phase contrast microscope contains a phase plate. phase contrast microscopy relies on the condenser to increase the contrast of an image. in brightfield microscopy, closing the condenser aperture will decrease the contrast of the speciment. stained cell speciments are best viewed by phase contrast microscopy.
Which of the following statements are true in the context of the microscope's field of view? I. It is the observable area within a circular space as defined by the lenses II. FOV is the smallest on the lowest power objective III. FOV is the maximum area visible through the microscope eyepiece IV. When you switch to a higher power, the field of zooms out towards the center
