Question

what is the difference between gram positive and negative bacteria i mark the answer brainliest please

Answer 1

GRAM POSITIVE BACTERIA:

1) Cell wall made up of peptidoglycan+teichoic acid.

2) Stain remain persistant.

3) Cell wall single layered.

4) Thickness of cell wall= 20-80 nm.

5) Teichoic acid present. It provides stability to the plasma membrane.

6) Only 2 rings in flagella present — S and M.

7) Very low lipid content.

8) Less bacteria are pathogenic.

GRAM NEGATIVE BACTERIA:

1) Cell wall made up of peptidoglycan.

2) Statin removes because stain is soluble in water and insoluble in lipid.

3) An additional layer of glycolipid is present in the cell wall.

4) Thickness = 8-12 nm.

5) Teichoic acid absent.

6) All 4 rings in flagella present — L,P,S and M.
