WebBacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells. In bacteria, chemical communication involves producing, releasing, detecting, and responding to small hormone-like molecules termed ... Web1 day ago · Chemical communication is a more versatile means of communication than electrical impulses. This is because there are many different types of signaling molecules, each with its own unique properties. Different signaling molecules can elicit different responses in receiving cells, allowing for a wide range of cellular communication.
