Cell are not discovered using electron microscopes.
False. Cells were first discovered by Robert Hooke in 1665 using a light microscope, long before electron microscopes were invented. The development of electron microscopes in the 20th century allowed for greater detail and resolution when studying cells.
Light microscope, also known as an optical microscope, can be used to study cells. Electron microscopes, including transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are also commonly used to study cells at higher magnifications. Fluorescence microscopes are utilized to visualize specific structures within cells using fluorescent markers.
why
Spicemen must be placed in a vacuum chamber. Since living cells cannot survive in a vacuum, they cannot be viewed using elctron microscopes.
"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

microscopes, such as light microscopes or electron microscopes. These tools allow scientists to visualize and analyze the different organelles and structures within cells at a high level of magnification. By using these techniques, biologists can gain insights into the internal workings of cells and better understand their functions.
SEM microscopes cannot view living cells because they require a high vacuum environment to operate, which would cause the cells to dehydrate and die. For viewing living cells, scientists typically use other techniques such as light microscopy or confocal microscopy that can be performed under conditions that keep the cells alive.
Scientists use electron microscopes, such as transmission electron microscopes (TEM) and scanning electron microscopes (SEM), to examine specimens that are smaller than what can be seen using a light microscope. These microscopes use beams of electrons instead of light to achieve higher resolution and magnification, allowing scientists to observe structures at the nanoscale.
Scientists using the earliest microscopes observed tiny organisms such as bacteria and protozoa for the first time. They also discovered that cells were the basic unit of living organisms, leading to the development of cell theory.
The specimen must be dead. Electron microscopes view specimens in a vacuum- no air.
No, optical microscopes cannot reach the magnification of electron microscopes. This is because of how electron microscopes work, they shoot a beam of electrons at the object and display the pattern that they reflect onto a specialized sensor, as opposed to optical that only display what photons are reflected using lenses that cannot zoom that far in.
Two scientists who studied cells using microscopes were Robert Hooke, who in 1665 was the first to observe cells in a piece of cork, and Anton van Leeuwenhoek, who in the 1670s observed single-celled organisms through his microscopes.
