Bacteria Within Biofilms Exchange

Question

Bacteria within biofilms exchange
A)plasmids.
B)quorum-sensing molecules.
C)nutrients.
D)All of the choices are correct.

Accepted Answer

Bacteria within biofilms exchange plasmids, quorum-sensing molecules, and nutrients. Plasmids are small DNA molecules that can be passed between bacterial cells, allowing for the exchange of genetic material. Quorum-sensing molecules are signaling molecules that bacteria use to communicate with one another, coordinating behavior such as the formation of biofilms. Nutrient exchange can occur within the biofilm matrix, allowing bacterial cells to share resources and increase their overall survival. Therefore, all of the choices listed are correct.
