Detailed explanation-1: -Quorum sensing (QS) is a cell density-dependent mechanism of communication between microorganisms, characterized by the release of signaling molecules that affect microbial metabolism and gene expression in a synchronized way.

Detailed explanation-2: -Bacterial cells within a population can act socially by coordinating their activities through cell-to-cell communication or ‘quorum sensing’. This collective behavior depends on the production and extracellular release of small signal molecules.

Detailed explanation-3: -Quorum sensing is a process of cell–cell communication that allows bacteria to share information about cell density and adjust gene expression accordingly.

Detailed explanation-4: -quorum sensing: Quorum sensing is a system of stimulus and response correlated to population density. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. density: A measure of the amount of matter contained by a given volume.
