how do cells of the onion specimen appear under the microscope
To make slides of cheek cells for microscopy, you will need a microscope slide, cover slip, swab or toothpick to collect the cells, a staining solution (such as iodine), and a microscope with at least 400x magnification. You may also need a pipette or dropper to apply the staining solution.
DAPI staining works by binding to the DNA in cells and emitting a blue fluorescent signal when exposed to ultraviolet light. This allows researchers to visualize the DNA in the cells under a microscope.
The development of the microscope and the use of staining techniques helped scientists see more details in cells. The microscope's magnification power allowed for the visualization of smaller structures within cells, while staining techniques enhanced the contrast between different cell components, making them easier to observe.
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
Staining microbial specimens allows for better visualization of their structures and morphology under a microscope. It increases the contrast between the cells and the background, making them easier to identify and study. Staining also helps to highlight specific features or organelles within the cells.
they are easier to see when you use a microscope
Staining with iodine solution caused the cells to change color based on the presence of starch. Starch-containing cells turned blue-black, while cells lacking starch remained unchanged. This allows for easier visualization and differentiation of cell types under a microscope.
Staining is used to enhance the visibility of plant cell structures under a microscope by adding color to certain components such as nucleus, cell wall, or cytoplasm. It helps in studying cell morphology, identifying different cell types, and locating specific organelles within the cells. Staining can also reveal details about cell health, division, and function.

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 used in plant cell staining to highlight the presence of starch. Iodine forms a complex with starch molecules, turning them blue or black, making them easily visible under a microscope. This staining method is commonly used to identify starch storage sites within plant cells.
