(DNA) via Pili from one bacterial cell to another
Glycocalyx - Correct Answer ✔✔ Slime layer for protection and adherence
Capsules - Correct Answer ✔✔ composed of mucoid (sticky) polysaccharides
Gram Positive - Correct Answer ✔✔ thick cell wall of peptidoglycan and the cell
membrane (traps the crystal violet)
