Specimens are placed in a vacuum (high vacuum, requiring a cryopump to get to 10^-7 torr. Then the specimen is bombarded with an electron beam (like getting a shock). Not likely that something could survive that.
For viewing a small living cell, an electron microscope would be more suitable as it provides higher resolution necessary to see detailed structures within the cell such as organelles. Compound light microscopes may not have enough magnification power to observe these structures in depth without damaging the cell.
The first scientist to observe living organisms with a microscope was Antonie van Leeuwenhoek in the 17th century. He is known as the "Father of Microbiology" for his groundbreaking discoveries using primitive microscopes of his own design.
The first scientist to observe living cells was Anton van Leeuwenhoek, a Dutch scientist, in the 17th century. He used a simple microscope that he designed and made himself to observe single-celled organisms in pond water, blood cells, and other living specimens. His discoveries laid the foundation for the field of microbiology.
The first scientist to observe and document tiny living organisms through a microscope was Antonie van Leeuwenhoek in the 17th century. He used his handmade microscopes to discover bacteria, protozoa, and other microorganisms, laying the foundation for the field of microbiology.
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.
A microscope.
No - because the power generated by the electron beam destroys any living tissue.
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.

Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.
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 is advantageous as it is more affordable, widely available, and can observe living specimens. However, it has lower resolution and magnification compared to an electron microscope, limiting its ability to visualize smaller structures in detail. Electron microscopes have higher resolution and magnification capabilities but are more expensive, have limited availability, and can only observe dead specimens due to the high-energy electron beams used.

A scientist would likely use a compound light microscope to observe a living one-celled organism. This microscope uses visible light to illuminate the specimen and allows for observing living organisms in real-time. Additionally, a phase contrast or differential interference contrast microscope could also be used to enhance the contrast of the specimen without staining.
