Solution

Gram-positive bacteria:

  1. Gram-positive organisms have a thicker peptidoglycan cell wall compared with gram-negative bacteria.
  2. The skin supports the growth of gram-positive bacteria, which protect the host from pathogenic bacteria.
  3. Gram-positive bacteria are called resident flora.
  4. They do not generally cause any diseases.
