Cheek cells are eukaryoticcells (cells that contain a nucleus and other organelles within enclosed in amembrane) that are conveniently burned from the mouth lining. It"s therefore straightforward toacquire them for monitoring.

You are watching: Why is it possible to easily collect cheek cells

Some of the main parts of acell include:

1. Cell membrane (external boundary of the cell)

2. Cytoplasm (the liquid within the cell)

3. Nucleus (at the center of the cell and controls cell functions)

4. Organelles (e.g. mitochondria-Organelles are cell frameworks withspecific functions)

Using biological stainssuch as methylene blue, it"s feasible to plainly observe and also distinguish thevarious components of a cell. This is bereason the stain will color some parts ofthe cell and not others, permitting them to be clearly oboffered.

How to Prepare a Wet Mount of Cheek Cells

Before starting, it"sconstantly essential to encertain that the working surchallenge is clean and also that you arewearing a pair of clean gloves to prevent contamination.

Cheek cells deserve to beeasily acquired by gently scraping the inside of the mouth making use of a clean,sterile cotton swab.

Once the cells have been derived,the complying with procedure is used for cheek cell wet mount preparation:

area a drop of physiological saline on a clean microscopic slide(central part of the slide)smear the cotton swab on to the facility (component containing the salinedrop) of the clean slide for around 4 seconds to gain the cells on to the centerof the slideadd a drop of methylene blue solution on to the smear and gentlyarea a cover slip on height (to cover the stain and the cells)any kind of excess solution have the right to be removed by poignant one side of theslide with a document towel or blotting paper.location the slide on the microscope for observation using 4 x or 10x objective to find the cellswhen the cells have been uncovered, they have the right to then be viewed at highermagnificatio


* Note - Used cotton swabsand cotton towel have to be safely discarded in the trash and not left lying onthe working table.

Why carry out we need to Stain the Cells?

The cell has differentparts, and those that have the right to absorb stains or dyes are referred to as chromatic.Having took in the stain, these parts of the cell come to be even more visible underthe microscopic lense and can therefore be quickly distinguished from various other components ofthe very same cell.

Without stains, cells would certainly appear to be practically transparent,making it tough to identify its parts.

Methylene blue has a stringaffinity for both DNA and RNA. When it comes in contact through the two, a darkerstain is developed and also have the right to be perceived under the microscope.

The nucleus at themain component of the cheek cell contains DNA. When a drop of methylene blue isintroduced, the nucleus is stained, which renders it stand also out and be clearlychecked out under the microscopic lense.

Although the entire cell shows up light blue incolor, the nucleus at the central component of the cell is a lot darker, which allowsit to be established.


On mounting the wet slide,the adhering to will be observed:

Large irconsistently shaped cells with distinctive cell membranes.A distinct nucleus at the main part of each individual cell(dark blue in color).


This is a basic and also funexperiment that will show youngsters the standard structure of a cell and also its majorcomponents. For simple identification of the components, the parent or teacher have the right to firstdisplay the youngsters some samples of the cells in breakthrough.This will certainly assist themidentify various parts with ease.

Once this has been accomplished, youngsters have the right to moveon to the following stage of discovering the features of these different parts.
