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,
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.
The difference between potato cells and onion cells, check cells, and lettuce cells is the presence of starch in the potato cells chloroplast organelles. The difference between cheek cells and the rest is easier the cheek cells do not have chloroplasts at all.
Onion cells have large vacuoles in their interior that store water molecules. Cells are arranged in a closely packed way in the onion tissue and hence appear as a brick wall when stained and viewed under the microscope.
No chloroplasts in cheek and onion cells
Stains were developed for different applications precisely because they make objects or features of objects easier to see and differentiate. The stains make things easier to see because they were made for that purpose.
Only you know that because you did the experiment not us.

we were able to see the different organells of the cells including cell wall ,plasma membarane,nucleous,cytoplasm mitochondria ,vacoules etc since we viewd from an electo microscope
The sweet onion is milder and easier to digest.
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
Onion cells have large vacuoles in their interior that store water molecules. Cells are arranged in a closely packed way in the onion tissue and hence appear as a brick wall when stained and viewed under the microscope.
No chloroplasts in cheek and onion cells
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
