goldfiish [28.3K]

Answer:

Gram positive; Contain thick mesh wall of peptidoglycan in cell wall.

Explanation:

  • Gram staining technique is used to separate the gram positive and gram negative bacteria on the presence or absence of thick layer of peptidoglycan in cell wall.
  • If a bacteria contain thick layer of peptidoglycan in cell wall it will retain the primary stain crystal violet (purple) and known as gram positive bacteria.
  • If bacteria don't have thick layer of peptidoglycan in cell wall the stain will wash out and it will give the pink color known as gram negative bacteria.
  • Peptidoglycan is glycoprotein or Glucose+Protein.
