"In electron microscope the object is viewed in highly vaccum conditions. Living cells would disentegrate in such a condition." This answer is not mine it comes from the "why can't electron microscopes be used to view cell structures" question
Living cells cannot be directly observed using an electron microscope because the vacuum environment and electron beam can damage or destroy the biological material. Additionally, living cells contain a lot of water which would evaporate in the vacuum, leading to cell shrinkage and distortion. To observe living cells, techniques like cryo-electron microscopy or fluorescence microscopy are used.
An EM is basically of 2 types. Scanning Electron Microscope and Transmission Electron Microscope. Yes definitely it is used to magnify and resolve specimens but a living specimen cannot be used. Only dead are used. This is due to certain disadvantages that come along with this microscope. If need further details over the microscope uses and types then let me know.yea...i completely agree wif yuh... :)
An Electron Microscope is used to study the contents of a nucleus.
Individual cells are not visible under an electron microscope because the resolution of the microscope is not high enough to distinguish the borders of individual cells. The electron microscope's resolution is limited by the wavelength of electrons used, preventing the visualization of single cells. Cells can be seen collectively as tissues or structures under an electron microscope.
A compound light microscope is commonly used to view living cells as it utilizes light to illuminate the specimen without damaging it. This type of microscope allows for observation of cells in their natural state, providing valuable insight into their behavior and functions.

A tunneling electron microscope cannot image live specimens.

The main disadvantage of an electron microscope compared to a compound microscope is that it requires a more complex and expensive setup. Electron microscopes also cannot be used to observe living specimens because the process typically involves vacuum conditions and sample preparation techniques that would kill living cells.

A light microscope uses visible light to magnify the specimen, allowing for observation of living cells and tissues. In contrast, an electron microscope uses a beam of electrons to achieve higher resolution and magnification, enabling visualization of smaller structures such as viruses and molecules.
