That's what she said to me last night when looking at my... hair.
The smallest diameter of a cell that can be resolved by a light microscope is typically around 0.2 micrometers, which is the limit of resolution due to the wavelength of visible light. Structures that are smaller than this limit will appear blurry or indistinct under a light microscope.
Common types of microorganisms that can be seen under a light microscope include bacteria, yeast, algae, and protozoa. These microorganisms are relatively larger and can be observed with a brightfield microscope at higher magnifications. Viruses, which are much smaller, typically require an electron microscope for visualization.
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.
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.
Cells can be seen under a microscope because they are transparent and the microscope uses lenses to magnify and focus light on the cells, making them visible to the human eye.

The smallest particle that can be seen with a light microscope is about 0. 2 microns. If an object is smaller than that, the light's wavelength cannot traverse it causing it to fall out of the visible spectrum.

yes
The organelles in a cheek cell that are not visible under a light microscope are the ribosomes. These organelles are responsible for protein synthesis.
A single atom is not visible in a microscope (it is too small to be imaged by photons). What you see in an optical microscope (or in general) is the light reflected, scattered, or emitted by the electron layers of the material under observation.

You can examine the cell under a light microscope. Eukaryotic cells have nuclei, and these should be visible under a light microscope.
