Yes, but special balls of ice that have layers, like an onion.
The onion's skin structure is natuarally arranged into thin layers, making it very convenient to prepare for the microscope slide. The process of slicing other plants into thin layers can be tedious, so for non-specialized, lower budget studies like schools, the onion is a natural choice.
Yes it would. The volatile oils in the membrane between layers of onion make your eyes water, provided the onion is sufficiently warm; if the onion is cold the vapours won't be released during cutting. For this reason, onions should be kept in the refrigerator; store them in a plastic bag, twisted to keep out the air. You can put them in several layers of plastic bags, or in a tightly-sealed plastic container so that they don't cause your refrigerator to smell of onions.
Onion cells, like most plant cells, have rigid cell walls which give them a regular shape. They are stacked tightly in columns and rows. Cheek cells have and irregularly shaped cell membrane. and are squished together in layers.
An onion bulb is made up of several layers. Cutting an onion in half, from the top to the root, will reveal the various layers.
Onion, cabbage, lettuce
it is 7 layers
Granite forms plutonsof igneous rock several kilometers below the surface as magmaslowly cools and crystallizes. The granite is under great overhead pressure.Then, granite is uplifted to the surface during a mountain-building event. During the mountain building process, the overlying rock iseroded as the granite is uplifted, and the pressure on the granite reduced. The granite expands and forms fractures or sheet joints parallel to the surface. The granite then erodes in concentric layers (similar to how an onion peels) forming rounded masses called exfoliationdomes.
I did an experiment in which i compared a small, medium, and large yellow onion's amount of layers. I found that all three specimens had 10-11 layers.
2 layers
Skins Layers, laminae
more than one cell cause of the many layers.

How many slices in an onion vary depending on how thinly the onion is sliced and how large the onion is when you begin. You might get 30 slices from a very large onion or more from a very thinly sliced onion.
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.
