The correct Answer is:
a
The technique of staining bcteria was given by a Dutach microbiologist Christian Gram and this technique is known as Gram staining. In the cell wall of grasm +ve bacteria both horizontal and wall vertical peptide linkage are present due to which mesh is dense and stain does not come out. Futher outer layer of cell wall of Gram+vbacteri is made up of techoic acid. In the cell wall of gram+ve bacteria, either horizontal or vertical peptide. linages are present, due to which comes out when washed with alcoho. Furyher outermost layer of ell wall of gramn -ve bacteria is made up lipopolysacchrides.
