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.
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,
Most of the organelles in the cytoplasm can be seen while stained, but not unstained. The big exception is the cell wall. I did this lab like two weeks ago.
Stained cells are always easier to see than unstained cells. However, when looking at an onion cell that is unstained, the cell wall can be seen.
The stained onion cells have anthocyanin in their cytoplasm, hence they look pink or red depending up on the amount of coloring material present in the cells.
Depends on how you are viewing the onion. If you are using a 100x magnification microscope, all you can usually see is the cell wall, and sometimes the nucleus.

Onion cells are plant cells, cheek cells are human cells and amoebas split? (i'm smart as well as beautiful, I also managed to keep my airhead image by putting a ? at the end, *giggles flirtily*)
.......... Did Ben ask this??????
An ELODEA cell is a PLANT cell. A HUMAN EPIDERMAIL cell is an ANIMAL cell. if you know that plant cells and animal cells have different organelles, then you should be good to go.
The cells of the onion appeared to be crooked.
Onion cells are arranged in a closely packaged way. This is so that they layers of the onion can be thick and tough.
Only you know that because you did the experiment not us.

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.
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
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
