Question

Why we use methane blue solution to check cheek cell under a microscope ?

Answer 1

Answer:

Explanation:

We use methane blue solution to colour the cells we place under the microscope. The solution highlights different part of the cell in different shades and allows us to observe properly. This is  not possible if we just look at the cells under the microscope without anything..

Hope this helps

Answer 2

Answer:

Methylene blue has a string affinity for both DNA and RNA.

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.
