Observations of the nucleus in human cheek cells
Answers
Explanation:
The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
Answer:
The inner lining of the mouth is composed of the basal mucosa which has the squamous epithelial cells. These cheek cells replicate every day and the dead cells are shed from the body. The cheek cells were scraped from the mouth and were examined as follows:
The cells of the inner lining of cheek were gently scraped using a toothpick, were transferred and spread in the water on the glass slide.
The cheek cells were stained with methylene blue for 2 minutes and mounted with glycerol.
The sides of the coverslip were attached to the microscopic slide with an adhesive tape and the specimen was observed in foldscope.
The foldscope containing the glass slide was placed on the stage of the compound microscope and was observed using the microscope’s 10 X objective lens
