Difference Between Gram Positive And Gram Negative Bacteria. The chief component of bacterial cell wall is MP PMT 1989 a Cellulose and chitin b Cellulose and pectin c Amino acids and polysaccharides d Cellulose and carbohydrates 12. The cell wall of gram positive bacteria has a thick peptidoglycan layer 20-30 nm while cell wall of gram negative bacteria has a thin peptidoglycan layer 8-12 nm.
Compared with Gram-positive bacteria Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. High murein content in cell wall. Amino acids cross-link peptidoglycan strands.
Quick Comparison between Gram-Positive and Gram-Negative Bacteria Serial Characteristics Gram Positive Gram Negative 1 Gram staining Stained purple or blue color color.
Gram - bacteria have lipopolysaccharides in their cell membrane which are ENDOTOXIC in Nature. Thinner layer of peptidoglycan single layer. CISCE ICSE Class 9. Bacteria whose cell has only a curvecomma is CPMT 1990 93.
