Question

Refer to the diagram below on Biofilm for Question 12 Signal NORP Binding to surface Matrix Signal Single-specles biofilim Irreversible attachment Growth and division, formation of matrix Mature biotam 12. According to the diagram, which ofthe following statement about biofilms is true? a Only one species of microorganism can inhabit any one biofilm. b. Bacteria are able to create a biofilm by attaching to a surface and secreting a matrix. c. Signaling molecules from the biofilm attract other organisms d. Both a and b e. Both b and c

Explanation / Answer

Answer is (E)----> both (b) and (c)

Because in process of biofilm formation first bacteria or microorganisms adhered to living or nonliving surface and then they produce extracellular matrix of polymeric substance, and encased within matrix


After that bacterial cells adjust their gene expression and communicate with other microbial cells that is called "quorum sensing" or Cell signalling and increase density of biofilm by attracting other cells.
