DESCRIBE THE EXPERIMENT TO OBSERVE THE NUCLEUS IN THE CHECK CELL
Answers
Explanation:
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. ... A deeply stained nucleus is observed at the centre of each cell.No prominent vacuoles are observed in the cells.
Answer:
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 Methyl 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 glycerin 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 center 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.
