Heat fixing is done to kill the specimen; adhere the specimen to the slide; and alter the specimen so that they more readily accept stains.
No. It is a staining on the cell itself.
as a couterstain
fixing the stain so that the first dye which is the crystal violet will not be washed away during rinse process.
This is known as a gram test.
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.
No. It is a staining on the cell itself.
Gram staining was devised by Hans Christian Gram of Denmark in the 1800s. (1853-1938)
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.

yes it is a special staining like other types....its importance is that one can identify the type of bacteria........
A basic dye used in gram staining is crystal violet.
no, it's eukaryotic. Gram staining is for bacteria.
