Under a compound light microscope, an onion cell will appear as a rectangular shape with a distinct cell wall and nucleus. The cell cytoplasm will be visible, with small structures such as vacuoles dispersed throughout. The onion cell may also have a clear membrane visible around the cell wall.
Onion epidermis is a suitable tissue for observing cellular structures with a compound light microscope because it is transparent, allowing light to pass through easily, and the cells are thin enough to view individual cells and structures such as cell walls, nuclei, and chloroplasts. Additionally, the large size of onion cells compared to other plant cells makes it easier to study their internal structures.
Staining with a dye such as methylene blue or eosin can be used to make the nucleus more visible in onion cells when observed under a compound light microscope. The dye selectively binds to different cellular components, allowing for better contrast and visibility of the nucleus.
The onion cell is missing chloroplasts, the organelles responsible for photosynthesis in green plants. Onion cells do not contain chlorophyll, so they do not require chloroplasts for photosynthetic processes.
You place it in a slide and you press it slowly against your body and down your leg. Once the smell is on your body, remove it and place under microscope. Make sure the light is on max for high visibility. Source: Facebook
To prepare an onion cell slide for microscopic examination, first peel off a thin layer of the onion skin. Place the thin layer on a microscope slide and add a drop of water to the onion skin. Gently place a coverslip over the onion skin to create a flat surface for viewing under the microscope. Finally, carefully place the slide on the microscope stage and adjust the focus to observe the onion cells.
Under a compound light microscope, you would not be able to see specific organelles like the lysosomes, peroxisomes, endoplasmic reticulum, and Golgi apparatus in an onion cell stained with iodine. These organelles are typically smaller and/or transparent, making them difficult to visualize with this type of microscope.

You should use iodine to stain the cells. Set the cells on a slide, let them dry you will repeat the process until it is completely covered in iodine and then you will slide it in the stage and then hopefully you will then see the sells of the onion skins.
Given a good microscope I can identify all parts of an onion cell.

The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
