the iodine stains the cell, so we can see the structures better. the nucleus is darkest
The cheek cells and skin cells are similar becuase they both are cells they are on the body.
Why do cheek cells need to be constantly replaced?
Onion cells are larger. Skin cheek cells are smaller probably due to the fact that they're overlapped or rolled up.
Cheek cells usually have a vacuole. The cheek cells are part of the human cells and are therefore classified as animal cells which usually have vacuoles.
When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.

iodine
It is much easier to extract DNA from the softer cellular structures of the inner cheek than the tougher exterior skin layers.
the cheek cell is not skin and so it is not like a finger, plus the finger cell would hurt much more, cheek cells are just a scraping with a touch of Iodine.
The cheek cells and skin cells are similar becuase they both are cells they are on the body.
Due to the techniques of obtaining the samples, onion cells remain intact in the tissue, but because cheek cells are obtained by rubbing a toothpick on your cheek, you are disrupting the cheek tissue, and instead of getting a sheet of cheek cells, you get individual cheek cells.
Cheek cells usually have a vacuole. The cheek cells are part of the human cells and are therefore classified as animal cells which usually have vacuoles.
Why do cheek cells need to be constantly replaced?
no
they are able to be able to connect
The cheek contains muscle cells, covered by epithelial cells.
cheek is eukaryotic multicellular and sexual
