Solution
The correct option is C Both A and B
The Gram-negative cell wall is characterised by the presence of outer membrane, a thinner peptidoglycan layer and extensive periplasmic space surrounding the peptidoglycan. It is composed of lipopolysaccharide and peptidoglycans. Gram-positive cells are characterised by the presence of the single thick layer of cell wall which is made up of peptidoglycan, teichoic acid and lipoteichoic acid. They lack outer membrane and porin and have narrow periplasmic space. Both Gram-positive and Gram-negative bacteria serve as plant pathogens causing diseases in them. Thus, the correct answer is option C.
