<span>The specimen are placed in vacuum while examining the cells or living organisms. Also, the electron must penetrate inside of the cell and in such conditions, any living organism is not able to survive. Thus, this reason best explains the answer to why dead cells specimen must be used for Transmission electron microscopy.</span>
