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.
2 layers
Onions cell structure is much like a brick wall. Little rectangles on top of each other, in each is a nucleus. You can see this when you look at a small sample of onion skin through a microscope. :D
When observing an onion cell under the microscope, it appear to be long an oval in shape. Staining the cell will make the chromosomes attain a deep purple color.

The easiest way to peel an onion is to cut off the top and bottom, make a vertical slit in the skin, and then peel off the outer layers.
The root cell's job is to gather minerals and and take it up the roots to the onion.
Tissue paper maney of layers and thick
It depends on the stain used when observing the cell.
Frog cells are eukaryotic animal cells that make up tissues and organs in frogs, while onion cells are eukaryotic plant cells found in the layers of an onion bulb. Frog cells contain specialized structures for functions like movement and nerve signaling, whereas onion cells have structures like a cell wall and chloroplasts for photosynthesis.
Platyhelminthes have three tissue layers: the outer ectoderm, the middle mesoderm, and the inner endoderm. This is known as triploblastic organization. These layers give rise to various organs and tissues that make up the flatworm's body.
Adipocytes are the cells that make up adipose tissue
What happens is the alcohol starts to shred the onion. Next alcohol is soaked up inside the onion which starts to make the onion shrink. The cell can't take the acid that goes in it shrinks and dissolves.
