As with people, it is vital for individual cells to be able to interact with their environment. In order to properly respond to externals stimuli, cells have developed complex mechanisms of communication that can receive a message, transfer the information across the plasma membrane, and produce changes within the cell in response to the message. The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms.
