Answer 1

Gram-negative bacteria:

2. They are the group of aerobic bacteria that do not retain the crystal violet dye during the procedure of Gram staining.

Gram Negative cell wall:

2. The cell envelope has 3 layers including, a unique outer membrane, a thin peptidoglycan layer, and the cytoplasmic membrane.
3. An outer membrane of the cell wall is a bilayer structure consisting of phospholipids molecules, lipopolysaccharides (LPS), lipoproteins, and surface proteins.
4. Endotoxin is toxins released by the cell during infections and function as receptors and block the immune response.
