Question

Explain the experimental process of observing nucleus in the cheek cells

Answer 1

Answer:

To Prepare Stained Temporary Mount of Human Cheek Cells

Real Lab Procedure

Gently scrape the inner side of the cheek using a toothpick, which will collect some cheek cells.Place the cells on a glass slide that has water on it.Mix the water and the cheek cells using  a needle and spread them.Take a few drops of Methylene blue solution using a dropper and add this to the mixture on the slide.After 2-3 minutes remove any excess water and stain from the slide using a blotting paper.Take a few drops of glycerine using a dropper and add this to the test mixture.Take a clean cover slip and lower it carefully on the mixture with the aid of a needle.Using a brush and needle, press the cover slip gently to spread the epithelial cells.Remove any extra liquid around the cover slip using a blotting paper.Place this glass side on the stage of the compound microscope and view it.

Observations

A large number of flat and irregular-shaped cells are observed.The cells do not have a cell wall. However, each cell has a thin cell membrane.A deeply stained nucleus is observed at the centre of each cell.No prominent vacuoles are observed in the cells.

Conclusion

As the cells observed do not have a cell wall, nor a prominent vacuole, the cells of the specimen on the slide are animal cells.

Answer 2

Answer:

• The process of observing nucleus in the cheek cells

Explanation:

• first we want a check cells .
• Then take that cheek cells in a watch glass and add some drops of saffronin or iodine and take that in a glass slide and cover with cover slip.
• Take the microscope and put that glass slide in microscope and observe the nucleus in cheek Cells
