Hormone
A hormone is a chemical messenger from one cell (or group of cells) to another. All multicellular organisms produce hormones including plants. The best-known animal (and human) hormones are those produced by endocrine glands of vertebrate animals, but hormones are produced by nearly every organ system and tissue type in a human or animal body.
