Plant hormones help coordinate growth, development, and responses to stimuli. A hormone is a signaling molecule produced in small quantities in one part of the body, and is then transported to other regions where it can bind to specific receptors and trigger a response. The hormone concept, which was originally derived from animal studies, was adapted to fit plants.

So the plant hormones fall into two basic categories. These three up here the auxins, gibberellins and cytokinins in general they tend to stimulate plant growth. While abscisic acid and ethylene can inhibit plant growth. So let's look at the first category, the auxins. One commonly mentioned auxin is IAA. And in general, the auxins are involved in cell growth and cell elongation. Especially.
In AP Biology (and the subject of biology as a whole), everything is connected. Tip 3: Hit Refresh. Remembering something right after you've studied it is one thing, and remembering it in the long term is another. After you get through a few sections of the AP Biology notes above, go back and do a quick review of all the information you've learned.
Chapter 45 Hormones and the Endocrine System Lecture Outline. Overview: The Body’s Long-Distance Regulators. An animal hormone is a chemical signal that is secreted into the circulatory system that communicates regulatory messages within the body. A hormone may reach all parts of the body, but only specific target cells respond to specific hormones. A given hormone traveling in the.

Plant hormones and growth regulators are chemicals that affect flowering, aging, root growth, killing of leaves, promotion of stem elongation, color enhancement of fruit, prevention of leafing, and many other conditions. Very small concentrations of these substances produce major growth changes. All plants produce hormones naturally, and growth regulators can be applied by people to are.
Plant hormones can be classified into five major categories, some of which are made up of many different chemicals that can vary in structure from one plant to the next. The classifications is based on chemical structural similarities and their effects on plant physiology. Each class has positive as well as inhibitory function and work in tandem with each other, interplaying to affect growth.
