Things that are very small, such as viruses, bacteria, and the detailed structure of cells, are only visible with an electron microscope due to their size being beyond the resolution of light microscopes.
An electron microscope bombards its target with electrons, while a traditional microscope uses visible light. Electrons can be resolved at considerably higher magnifications that visible light (due to their smaller wavelength).
An electron microscope uses a beam of electrons to illuminate the specimen, creating an image with higher resolution and magnification than a light microscope. The electron beam interacts with the specimen, producing signals that are used to generate a detailed image of the sample's surface or internal structure. Electrons have shorter wavelengths than visible light, enabling electron microscopes to visualize objects at a much smaller scale.
An electron microscope can reach a far greater magnifiction than a conventional microscope. It is obvious that the largest advantage of any type of microscope is to observe an organism that can not be seen by the unaided eye. Light microscopes are easy to use, can magnify up to 2000 times, enable magnification of live cells and their movement, and are relatively cheap compared to electron microscopes. The only disadvantage is that it can only magnify up to 1000 times, after that the image is blurry, whereas an electron microscope can magnify up to 100,000 times! However, electron microscopes are extremely expensive, difficult to use, and cannot observe live specimens.
The resolving power of an electron microscope is limited by the wavelength of the electrons being used, which is much smaller than that of visible light. Additionally, aberrations in the electron optics and sample distortion can also limit the resolution.
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.
The light microscope use the visible light; the electron microscope use an electrons beam.
A microorganism is a very tiny organism, only visible in an optical or electron microscope.
Flagella are typically only visible through an electron microscope due to their small size, which is on the order of a few micrometers. Light microscopes do not have the resolution necessary to clearly visualize structures at this scale.
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.
An electron microscope bombards its target with electrons, while a traditional microscope uses visible light. Electrons can be resolved at considerably higher magnifications that visible light (due to their smaller wavelength).
Bacteria can only be seen with the aid of a microscope, as they are typically very small and not visible to the naked eye. A compound light microscope or an electron microscope is commonly used to observe and study bacteria.

Bacteria have no organelles.
A light microscope uses visible light to illuminate a sample and magnify its image, making it suitable for observing living cells and larger biological structures. In contrast, an electron microscope uses a beam of electrons to create a highly detailed image of the sample at a much higher magnification, enabling the visualization of smaller structures such as viruses and proteins.
viewing objects too small to be seen with visible light.
Optical microscopes use visible light to magnify objects, providing lower resolution images compared to electron microscopes which use beams of electrons to achieve higher magnification and resolution. Electron microscopes are able to see smaller objects in more detail due to the shorter wavelength of electrons compared to visible light.
The thin boundary of a vacuole, known as the tonoplast, may or may not be visible under a light microscope depending on the staining used, the type of vacuole, and the resolution of the microscope. In most cases, you would need an electron microscope to clearly visualize the tonoplast.
