What are the different types of microscopy and staining and when are they used? CORRECT ANSWER Types of microscopy include: light microscopy- used primarily to get an idea of the form of the bacteria, used in combination with staining to get an idea of Gram positive and Gram negative protein. Green fluorescent is used to observe cell occurrences like binary fission and movement of proteins. 
Electron microscopy is very detailed at getting an idea of what is occurring inside and outside of the ce...
