The discovery of cells is credited to Robert Hooke in the 17th century, who observed them under a simple light microscope. However, electron microscopes have allowed for greater visualization and understanding of cell structure and function at a much finer level of detail.

The ability to achieve much higher magnifications and resolutions than light microscopes due to a much shorter wavelength of electrons. Transmission electron microscopes can visualize structures at the atomic level, which is not possible with light microscopes.
Electron microscopes offer much higher resolution and magnification capabilities compared to light microscopes. They allow for visualization of smaller structures and details, such as individual molecules, viruses, and cell organelles. Electron microscopes also have the ability to produce 3D images and can differentiate between materials based on their electron densities.
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
Electron microscopes have a high resolution, allowing for detailed imaging of small cellular structures. They can magnify objects up to 2 million times, revealing intricate details within cells that may not be visible with a light microscope. Additionally, electron microscopes can provide information about the internal structure of cells, such as organelles and molecules.
