WebCommunicating cells may be close together or far apart. Multicellular organisms release signaling molecules that target other cells. Cells may communicate by direct contact. Both animals and plants have cell junctions that connect to the cytoplasm of adjacent cells. In biology, quorum sensing or quorum signalling (QS) is the ability to detect and respond to cell population density by gene regulation. As one example, QS enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial. … Meer weergeven Quorum sensing was first reported in 1970, by Kenneth Nealson, Terry Platt, and J.
