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 type of plant produces tea?
The tea plant, although tea can be made out of many other plants.
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.
If hormones travel in the bloodstream why don't all tissues respond to all hormones?
The tissue/cells need a receptor that can interact with that hormone in order to respond to it. This receptor may be on a cell membrane, inside the cell, or even inside the nucleus (in the case of steroid hormones, for example.) Like many organic chemicals in the body, they have structures which result in certain parts of the molecule being presented to cells (active sites). Because cells and tissue have different structures as well, only certain cells will react to the presence of a particular hormone. Many hormones have antagonist hormones that cause an opposite effect. This helps control negative feedback when the target organ's hormone levels are too high.
What hormone does the hypothalamus gland mke?
The hypothalamus makes many hormones, even more than the pituitary gland. A couple of these are oxytocin and melatonin. It also makes many stimulating hormones that trigger the pituitary to make its hormones to control other glands.
How many cells does a plant have?
A full grown plant has about 50,000,000 cells.
What is an edible seed of bean plant called?

What is the glands that produce the egg and cells hormones?
In females the egg develops in the ovaries, this is also where estrogen and many other female hormones are produced.
What does the hypothalamus conrol?
The hypothalamus is the part of your brain responsible for making hormones. These hormones regulate many processes in the body such as wanting to sleep, eat, and drink.
What is a flowering plant that grows on a stalk with many small flowers?
There are many flowers that are made of small clusters of flowers such as Baby's breath, forsythia, goldenrod, and others.
What is the job a a receptor molecule?
A receptor molecule is a molecule that receives information from outside the cell. They are embedded in either the plasma membrane or cytoplasm of a cell. A specific molecule on the surface or inside of a cell with a characteristic chemical and physical structure. Many neurotransmitters and hormones exert their effects by binding to receptors on cells.
How is a thermos made?
a themos is made in many parts. A first coat a insulator then the inside coat is filled with a substance called foam tissue a material that finds the mold of its insulator
Beauty is only about looks?
Many consider that true beauty does not mean only physical appearance. It is also the beauty inside of a human being. Many consider true beauty as the beauty of the inside from there many proverbs have been made, one of them being “Beauty is skin Deep”. Visit now
