Staining of human cheek cell - First we have to take a clean piece of cotton swab and scrap the epithelium layer from the inside of our mouth. It is then put on the previously cleaned slide and smear is prepared. Then a staining solution called haematoxylin is added as a colour solution. Then the excess stain is removed and cover slip that is previously cleaned is added to the slide to make it appropriate for looking under microscope. Then the cheek cells are observed under microscope.
Human cheek cells are observed under microscope-
1. Cells are polygonal or flat in shape and structure –
2. They have irregular cellular thin boundaries which contains jelly like cytoplasm and the cytoplasm are granular.
3. This cell do not have plastids, vacuoles or cell wall.
4. They are generally made up of squamous epithelium cells.
Cell Wall – As animal cells do not contain any cell wall .So the cheek cell of the human embryo do not contain any cell wall.
Cell Membrane – Cell membrane are very thin border of the cells of the animal.
