  1. Their cell wall is only single-layered and 100-200 A thick.
  2. They can be stained by gram stain.
  3. They do not have pili.
  4. In gram positive bac-teria, there are mes- osomes.
    Gram negative bacteria :
    1.Their cell wall consist of two layers and is 70¬120 A in thickness.
    2.They cannot be stained by gram stain.
    3.They do have pili.
