Vedclass · Answer

(A) Gram-negative bacteria possess a thin peptidoglycan layer and an outer membrane rich in lipids.When treated with alcohol,the lipid-rich outer membrane dissolves,allowing the crystal violet-iodine complex to wash out,which is why they do not retain the stain.The outer membrane of Gram-negative bacteria indeed contains lipopolysaccharides $(LPS)$,which are integral components of the outer leaflet of the outer membrane.Therefore,both the Assertion and the Reason are correct,and the presence of the lipid-rich outer membrane (containing $LPS$) is the reason why the stain is not retained.

Assertion: Gram-negative bacteria do not retain the stain when washed with alcohol.
Reason: The outer face of the outer membrane of Gram-negative bacteria contains lipopolysaccharides,a part of which is integrated into the membrane lipids.
