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.

What plant organelle is missing from the onion cell?
Because, it is very small. You will need a electron microscope to see it.
How do cells of the onion specimen appear under the microscope?
The cells of the onion appeared to be crooked.
Why can we just see vacuole nucleus cell membrane and cell wall in onion cell under light microscope and not other organelles?
Onion epidermal cells occur mitosis (nuclear division) and cytokinesis(cell division). Interphase cell typically have one or more number of nuclei, so a few nuclei do not appear next to a cell wall.
What structure observe in onion epidermal cells are not present in human epithelial cells?
The structure of onion epidermal cells refers to the arrangement of tissues in this cells. You can find the structure of onion epidermal cells online athttp://biology.touchspin.com/onion_epidermis.php. The structures observed in an onion epidermal cell, which are not present in the human epithelial cells are cell wall, central vacuole and vacuolar membrane.

Why do you use the onion for cell sample and not the leaf?
An onion is easy to peel to 1 layer of cells, and with a light microscope you cant see the individual cells in a leaf. Also the cell obtained from the bulb of onion is colorless, hence it can be easly stained with different dyes to study the cell organells under the microscope.

What part of an onion cell can you identify?
Given a good microscope I can identify all parts of an onion cell.
What cell structures can be seen in a stain 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,
When you see a specimen clearly down a microscope it is in an onion?
