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.
synaptic an electrical signal along a nerve cell triggers the secretion of neurotransmitter molecules carrying a chemical signal that diffuse across the synapse, triggering a response in a target cell 4. How does a hormone qualify as a long-distance signaling example? In endocrine signaling (hormonal signaling in animals), hormone molecules are released by specialized cells, which travel to other parts of the body through the circulatory system to reach target cells that recognize and respond to the hormones.
