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.
Overview [edit]. Cell Signaling is an important facet of biological life. It allows cells to perceive and respond to the extracellular environment allowing development, growth, immunity, etc.Additionally, errors in cell signaling may result in cancer growth, diabetes.n the third type, the signal is transmitted directly from the cytoplasm of one cell through small conduits into the cytoplasm of an adjacent cell. Paracrine signaling is a form of cell signaling in which the target cell is near the signal-releasing cell.
