Expert Answer:

  • The main purpose of staining or adding dyes to the microbial smear is to make the microbes visible under microscope. 
  • Gram staining is performed to distinguish between gram positive and negative bacteria as they have different characteristics.
  • Certain cellular components can also be viewed by staining. 
  • Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.
