Question

The cheek smear slide is made by taking a q-tip or toothpick, rubbing it on the inside of your mouth (to remove cells) and then wiping or smearing it onto a blank slide. A stain is used on the cells so that you can see them, otherwise, they would be see-through.

Look at the cheek smear slide using the 10x objective (total magnification of 100x). Approximately how many cells do you see inside the red circle?

Select one:

a. 5

b. 10

c. 50

d. 100

Answer 1

Ans. Though it depends on the sample. But at the very least 10 cells will be observed.

Thus the answer is b.10

These cells are usually stained by methylene blue.

Under the microscope large irregularly shaped cells are observed with distinct cell membranes.
