Answer;
-Special stains
Step-by-step explanation;
-Cell staining is important in the diagnosis of microorganisms because bacteria can be identified by the color differentiation of stains (dyes).
-Microscopic examination of stained cell samples allows examination of the size, shape, and arrangement of organelles, as well as external appendages such as the whip-like flagella, which are the cell's organs of motion. When sample cells are stained to show their chemical composition it is called differential staining.
-Special stains are used to help visualize and/or identify structures and substances in sections.
