Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.
