The slide is colored with purple and red stains, then examined under a microscope. The color of stain picked up and retained by the bacteria (purple or red), their shape (such as round or rectangle), and their size provide valuable clues to their identity
The primary stain used in Gram staining is crystal violet.
The mordant used in the process of gram staining is called crystal violet.
The classification of cyanobacteria is based on Gram staining, which is typically negative.
Gram positive bacteria stain purple in the Gram staining technique because they have a thick layer of peptidoglycan in their cell walls, which retains the crystal violet dye used in the staining process.

Gram staining was devised by Hans Christian Gram of Denmark in the 1800s. (1853-1938)

No, gram staining and flagella are not directly related. Gram staining is a technique used to classify bacteria based on cell wall characteristics, while flagella are thread-like appendages that help bacteria move. Flagella presence or absence does not affect the results of a gram stain.
Differential staining is the procedure that are used to distinguish organism based on their staining properties. Use of gram stain divide bacteria into two classes - gram positive which retain crystal violet stain purple colour, gram negative which lose their crystal violet and give pink colour. By this method we can differentiate two different types of bacteria having different cell wall composition that is the reason gram staining used widely as differential staining

It tells the microbiologist/clinician facts about the cell wall construction of the bacterium. This then indicates which antibiotics to prescribe if you are trying to get rid of a bacterial infection.
No, iodine is not a basic stain. Iodine is commonly used in Gram staining to identify bacteria as either Gram-positive or Gram-negative based on their cell wall composition. It acts as a mordant in the staining process and helps to fix the crystal violet stain in Gram staining.
