Final answer:
The transmission electron microscope is useful for viewing thin structures, the scanning electron microscope is useful for finding shape and surface texture, and the compound microscope with a massive stain is good for general observation.
Step-by-step explanation:
The transmission electron microscope (TEM) focuses a beam of electrons through an object and is especially useful for viewing thin structures such as cells and cell organelles. It provides high magnification and resolution, allowing scientists to see individual atoms and the structure of cell nuclei. An example of a TEM is Figure 2.28.
The scanning electron microscope (SEM) allows scientists to find the shape and surface texture of extremely small objects. It slides a beam of electrons across the surface of a specimen, producing detailed maps of the surface. SEM is useful for viewing thick structures such as biofilms, as mentioned in Figure 2.30.
The compound microscope with a massive stain is a brightfield microscope that uses a stain to enhance the contrast of the specimen. This type of microscope is commonly used in laboratories and schools for general observation of biological samples.
