How does auxin produce phototropism?
Auxin accumulates on the lower surface of the root and inhibits elongation of cells in that region.
What effect does auxin on plant roots?
slow cell growth
The effect of auxin depends on the target tissue?
true
What is the effect of auxin in shoots called?
Greater concentration of auxin in the cells facing light restrict cell elongation whereas on the other side (away from light) more elongation of cells takes place due to optimum amount of auxin. thus, the shoots turn towards light.
Which substance produced in one part of a plant affects another part?
A hormone called auxin, which is produced in the apical meristem or shoot tip of a plant, can affect the growth and development of other parts of the plant. It can regulate processes such as cell elongation, root development, and leaf growth. Auxin moves through the plant's vascular system and can affect different tissues and organs.
What is the chemical produced growing in root tips?
Auxin hormone
What is the hormone for root?
auxin
Does auxin induce root initiation?
yes
What are Three ways that auxins effect plant growth?
Auxin promote stem elongation. This plant growth hormone is responsible for development of root system. Apical bud undergoes rapid division under the influence of auxin.
What chemical is produced in growing root tips?
Auxin hormone
How does auxin produce phototropism?

What effect does auxin on plant roots?
slow cell growth
The effect of auxin depends on the target tissue?
true
What do fruit tissues do in response to auxins?
an auxin is basically a cloning agent. You would dip the plant route in to the auxin powder ans then plant the root and it would grow:) This linked with selective breeding
What effect does auxin have on plant roots?
slows cell growth
What is the effect of auxin in shoots called?
Greater concentration of auxin in the cells facing light restrict cell elongation whereas on the other side (away from light) more elongation of cells takes place due to optimum amount of auxin. thus, the shoots turn towards light.
Why do a plants roots always grow downwards and its shoots always grow upwards?
the stimulus in this case is gravity .shoots grow up,away from gravity.roots grow down,towards gravity.again auxin control this growth.if a plant is put its side the auxin builds up on the lower side of the shoot and the root.in the shoot the auxin stimulates it to grow moreon the lower sidethis causes the shoot to bend upwardsin the root the auxin also builds up on the lower side.but Ayxin slows down growth in a rootso tht upper side of the root grows quicker than the lower sidethe root bends downwards
