Hormones are chemical signals that coordinate the various parts of an organism. A hormone is a compound produced in one part of the body which is then transported to other parts of the body, where it triggers responses in target cells and tissues. Overview: Stimuli and a Stationary Life. Plants, being rooted to the ground, must respond to environmental changes that come their way. For example, the bending of a seedling toward light begins with sensing the direction, quantity, and color of the light. . Red Hake . Urophycis. . chuss. .
