Which microscope you choose depends on what you are using it for, if you are looking for very small sub cellular structures such as ribosomes or bacterial cells then you need an electron microscope, but if you need to just see a tissue or a cell as a whole then use an light microscope...
It is difficult to see the cell or its components due to their very minute size , So, the cell discovery was related to the invention of the microscope ,
Microscope Light Microscope Electron Microscope Light Microscope (LM) The Magnification power of the LM is limited to 1000-2000 X. The Resolving power (resolution) of the LM is 0.2 µm. The resolving power (resolution) is defined as the smallest distance between two particles at which they c...

Electron microscope, microscope that attains extremely high resolution using an electron beam instead of a beam of light to illuminate the object of study. Fundamental research by many physicists in the first quarter of the 20th century suggested that ca
Sporulation in the Trematode Hyperparasite Urosporidium crescens De Turk, 1940 (Haplosporida: Haplosporidiidae): An Electron Microscope Study The ultrastructure of spore formation starting with multinucleated plasmodia was investigated in Urosporidium crescens, a haplosporidan pathogen of metacer......
The structure of the epithelial cells of the alimentary tract ofFasciola hepaticawas investigated by means of light and electron microscopy. Tissue prepared for electron microscopy was fixed in 1 per cent osmium tetroxide, buffered with veronal to a pH of 7.4, and embedded in butyl methacrylate ...
The smallest thing you can see with a microscope is determined (partly) by the light that shines through it. An ordinary light microscope uses photons of light, which are equivalent to waves with a wavelength of roughly 400–700 nanometers. That's fine for studying something like a human ...
Finally, whilst the imaging capabilities and resolution of an SEM are far greater than a light microscope, it commonly has a detection limit of approximately 0.1% weight/weight (w/w), and hence cannot detect elements present in trace concentrations. SEM-EDS is most useful for the determination...
