Question

The lipopolysaccharide layer (LPS) is a characteristic of the wall of ________.

archaean cells
Gram-negative bacteria
bacterial prokaryotic cells
eukaryotic cells

Answer 1

Gram-negative bacteria

Step-by-step explanation:

Gram-negative bacteria are classified by the color they acquire after undergoing a chemical process called Gram stain. In this process, Gram-negative bacteria, which have a thinner polysaccharide wall (relative to gram-positive bacteria) that do not retain the violet crystal (used in gram staining) during the discoloration process and are red in color. final coloring process.

Gram-negative bacteria turn red when using this process. The other bacteria get blue in color. They are called Gram positive. Gram-negative and Gram-positive bacteria are different in color because their cell walls are different. They also cause different types of infections and different types of antibiotics are effective against them.

Gram-positive bacteria retain the violet crystal due to the presence of a thick layer of polysaccharides. Gram-negative bacteria have a thinner polysaccharide wall.
