What are advantages and disadvantages of staining a sample?

Answer 1

Some cells produce gram-variable results.

Some cells produce no results.

The age of the culture can influence the results.

It has limited usage in environmental Biology and is not as good as molecular techniques.

Answer 2

Different types of materials show up different colors under the gram stain process. For example, gram positive bacteria vs. gram negative bacteria show up differently (as colors) under the microscope using the gram stain vs. the simple stain. You get a blue or purple for a gram positive and a red for a gram negative.

Answer 3

the advantage of staning a sample is that it helps in the identification of the sample by mere colour change without getting into the complete analysis of the sample The disadvantage could be that the cost of stain used for colouration..

Answer 4

Two advantages are that
A: You can see the entire cell and organelles
B: You pick specific organelles to view depending on what stain you use.

Two disadvantages are:
A: It can kill the cell.
B: The stain choosen has to be very specific.

Answer 5

gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.

Answer 6

Advantages of staining a sample include enhancing contrast, highlighting specific structures, and aiding in the visualization of cells or tissues. However, staining can introduce artifacts, alter cellular morphology, and require additional processing steps that may impact the accuracy of the results.

Answer 7

easy to observe the morphology,size and shape are the advantages but disadvantages are that sometime distrotion of the cell wall may occur.
