Question

how do you observe nucleus in human cheek cell​

Answer 1

Answer:

HEY MATE

THE ANSWER IS

Cheek cells are eukaryotic cells (cells that contain a nucleus and other organelles within enclosed in a membrane) that are easily shed from the mouth lining. It's therefore easy to obtain them for observation.

Answer 2

Explanation:

Take a clean cotton swab and gently scrape the inside of your mouth.

Smear the cotton swab on the centre of the microscope slide for 2 to 3 seconds.

Add a drop of methylene blue solution and place a coverslip on top. Concentrated methylene blue is toxic if ingested. Wear gloves and do NOT allow children to handle methylene blue solution or have access to the bottle of solution.

Remove any excess solution by allowing a paper towel to touch one side of the coverslip.

Place the slide on the microscope, with 4 x or 10 x objective in position and find a cell. Then view at higher magnification.

Human Cheek CellMethylene blue stains negatively charged molecules in the cell, including DNA and RNA. This dye is toxic when ingested and it causes irritation when in contact with the skin and eyes.

The cells seen are squamous epithelial cells from the outer epithelial layer of the mouth. The small blue dots are bacteria from our teeth and mouth.
