quorum sensing

This term is a specialized biological concept used primarily in microbiology and genetics. It describes a chemical communication process that allows single-celled organisms to act as a multicellular unit once a specific population threshold is reached. The term carries a connotation of coordination and collective intelligence among microorganisms.

Because it refers to a specific biological mechanism or process, it is treated as an uncountable noun. It does not have a plural form in standard scientific discourse, as it describes the phenomenon itself rather than individual instances of the process.
