Chapter 37, Problem 3TY
Summary Introduction
Introduction: An organism’s response to an external or an internal stimulus is known as its behavior. Plant movement is one of the examples of plant behaviour. The plants respond to stimulus such as light, gravity, and sometimes touch. Plant hormones are employed to provide response to a stimulus. Some of the examples of plant hormones are auxins, cytokinins, gibberellins, ethylene, abscisic acid, and brassinosteroids.
