Detailed explanation-1: -TEM is often used to obtain detailed images of the internal structures of cells.
Detailed explanation-2: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.
Detailed explanation-3: -The electron microscope is necessary to see smaller organelles like ribosomes, macromolecular assemblies, and macromolecules.
Detailed explanation-4: -A transmission electron microscope would be ideal for viewing the cell’s internal structures, because many of the internal structures have membranes that are not visible by the light microscope.
Detailed explanation-5: -Two types of electron microscopy-transmission and scanning-are widely used to study cells. In principle, transmission electron microscopy is similar to the observation of stained cells with the bright-field light microscope.
