Question

bacteria stained by........​

Answer 1

Bacteria is stained by gram-staining.

Explanation:

• Gram staining can be defined as a technique by which researchers are able to distinguish bacterial microorganisms into two main types.

• Gram positive and gram negative are the types of bacteria which are distinguished using gram staining.

• As gram positive bacterial have a thick cell wall, hence they attain the colour of the stain which is violet.

• Gram negative bacteria, on the other hand, attain pinkish color as a result of staining.

Answer 2

Answer:

bacteria stained by gram-staining.

Explanation:

Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process.
