Differentiate gram positive bacteria from gram negative bacteria by giving two points each.
Answers
Answer:
The cell wall of gram-positive bacteria is consisting of thick layers of peptidoglycan. Whereas the cell wall of gram-negative bacteria is consisting of thin layers of peptidoglycan. During the gram staining procedure, a gram-positive cell retains the purple-colored stain.
Peptidoglycan Layer: It is a thick layer/ also can be multi-layered.
Cell Wall: A single-layered, smooth cell wall.
Cell Wall thickness: The thickness of the cell wall is 20 to 80 nanometres.
Outer membrane: The outer membrane is not present.

Answer:
Gram positive bacteria:-
1. Gram positive bacteria have a thick peptidoglycan layer and not outer lipid membrane .
2. Gram positive bacteria produce exotoxins.
3. During the gram staining procedure, a gram positive cell retains the purple- coloured stain. But do not retain the purple colou stain.
Gram negative bacteria:-
1. The cell wall of gram- negative bacteria is consisting of thin layers of peptidoglycan
2. Gram- negative bacteria produce endotoxins
3. Gram negative bacteria cause many infectious in humans. Some common illness in indigestion, rood poisoning, pneumonia, meningitis etc. Some other in fectious also happen in the blood cells, bloodstream wound infectious, etc, due to these bacteria
