Light microscopy CORRECT ANSWER - Uses visible light to examine microscopic-sized objects that cannot be seen by the naked eye. - Allows finer detail than the naked eye. Electron microscopy CORRECT ANSWER - Visualize objects much smaller than those resolved optically. - Use accelerated electrons instead of light photons. - Samples are fixed with chemicals to cross-link molecules to preserve their structure. Fluorescent stains CORRECT ANSWER - Used with light microscopy. - Fluorescence ...
