Answer: A group of bacteria that accumulate in layers and secrete an protective extracellular material

Explanation:

Biofilm comprises any spectrum of microorganisms, including pathogens in <u>which cells stick to each other and to a surface</u>, so they become adherent cells. These cells become embedded within an extracellular matrix that is composed of extracellular polymeric substances (polysaccharides, lipids, proteins and DNA) which surrounds and protects cells. <u>For this reason, bacterial biofilms cause chronic infections because they show increased tolerance to antibiotics.</u>
