In general, it is accepted that there are five major classes of plant hormones, some of which are made up of many different chemicals that can vary in structure from one plant to the next.
The chemicals are each grouped together into one of these classes based on their structural similarities and on their effects on plant physiology. (following this is a list of the five major classes)
Other plant hormones and growth regulators are not easily grouped into these classes; they exist naturally or are synthesized by humans or other organisms, including chemicals that inhibit plant growth or interrupt the physiological processes within plants. Each class has positive as well as inhibitory functions, and most often work in tandem with each other, with varying ratios of one or more interplaying to affect growth regulation.

What else can I help you with?
Are plant hormones an example of an internal stimuli?
Yes many plant hormones are secreted by plants internally. Such as auxin, gibbrailin, cytokinin etc.
What chemical made by an endocrine gand?
Hormones are made by endocrine glands, of which there are many.
What plant are inside?
Many plants can live inside. Here are some examples: Ferns Banzai
What are topic hormones?
These hormones stimulate the secretion of other hormones. Many hormones of hypothalamus are topic hormones.
What is the name of the chemical that controls plant growth?
The plant growth hormone Auxin is controlled by circadian rhythms within the plant. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.
Is a chloroplast in a plant?
Yes also,because there are so many present inside, it what makes it green.
Noodles is there any any hormones in it?
Yes, there are many hormones in it!
What is the cell wall of plant cell made of?
the cell wall of a plant cell is made up of many different things like sugars and cellulose. It can be made up of many different things though.
What type of plant produces tea?
The tea plant, although tea can be made out of many other plants.
What is a plant that grows in china many things are made from this plant it is eaten by pandas it starts with a b?
The plant you have described is a bamboo plant, many things are made from it (ie; baskets, chairs, table, clothes) and it is also a popular household plant in North America for its supposed "lucky" qualities. The bamboo plant is one of the main food sources of the panda.
Why are normal animal and plant cells not considered unicellular organisms?
Because it has many cells inside to do works efficiently within the cell. Because it has many cells inside to do works efficiently within the cell.
What are processes affected by plant hormones?
A hormone is a chemical that affects the ways in which an organism functions; it is produced in one part of the plant (or animal) body but affects many other parts of the body as well. Hormones work by coming in contact with target cells, causing the organism to respond in various ways to the chemical signal. In plants, hormones usually work by influencing cell differentiation, elongation, and division. They also affect the timing of reproduction and germination. These hormones are divided int o five categories: auxins, cytokinins, gibberellins, inhibitors (or abscisic acid), and ethylene.
