how do cells of the onion specimen appear under the microscope
All it does is make the cells an easy to see color rather than clear or pale. The parts of the cells are darkened by the stain so you can see them better.
Most cells contain structures that are transparent and without color, which makes visualization difficult, even with the aid of a microscope. Cell staining is used to gain more information about cells and tissues, and allows for the structures within cells to be seen in great detail
People use iodine on plant cells because it reacts with the starch in the cell causing it to change colour and allowing you to see it through a microscope
Light microscope were used to discover cells
There are many disadvantages to stain and not staining cells before viewing them. One disadvantage of gram staining is that the cells cannot be alive while being stained, so viewing live stained cells is impossible.
Without the microscope we wouldn't know as much about cells as we do now with microscopes and we probably would be more prone to sickness considering that sickness has to do with cells fighting against virus' and the cure is hidden with the factors of the cell.
It will make them stand out more under a microscope
they are easier to see when you use a microscope

By the shape and appearance changes.
The combination of Congo red cream and distilled water is used for staining cells for viewing under the microscope. Staining make the individual cells much easier to see.
Plant cells, animal cells and bacteria can be visualized through the light microscope. Although some of these samples may require staining in order for the observer to see them, the magnification offered by the light microscope is sufficient to look at the morphological structures of the types of cells mentioned above
There are several uses for a staining jar. In microscopy, it is used for staining tissues and cells for slides. After being stained with dyes or stains, the specimens can also be placed in the jar to look for certain aspects.

Iodine is commonly used to see cells clearer under a microscope. Any chemical with staining properties can serve the same purpose.
Cells tend to be rather transparent under the microscope, and staining them makes it much easier to see the internal structures.

Sperm cells are way too small to see with the naked eye. You need a microscope to see the individual cells. Now you can see semen as a whole without a microscope, and semen is usually cloudy white in appearance.
