The transmission of a signal through the nervous system can also be considered an example of long-distance signaling. Local signaling in plants is not well understood. Because of their cell walls, plants must have different mechanisms from animals. Plants and animals use hormones for long-distance signaling. In animals, specialized endocrine cells release hormones into the circulatory system, by which they travel to target cells in other parts of the body. Plant hormones, called growth regulators, may travel in vessels but more often travel from cell to cell or move through air by diffusion.
Cell signaling occurs by 2 methods, electrical and chemical signals. Cells receive information from their environment, usually in the form of electrical and chemical signals. So Cell signaling is a way for a cell to receive information from it environment.embrane receptors allow cells to recognize, transmit, and respond to a variety of specific signals. A technical definition I found is: Cell Signaling-all living cells sense and respond to their enviroment by a set of mechanisms known as cell signaling.
