Many bacteria exist in biofilms in nature. Based on the information in the passage and in the chapter, is it possible to create a pure culture of a species that normally exists in biofilms?

(B) Yes, because bacteria are most commonly found in sessile forms and a biofilm contains sessile bacteria.
(C) No, because a pure culture by definition must grow in medium and would not be able to form a biofilm.
(D) No, because biofilms always contain many species of bacteria and a pure culture does not.
