Is auxin a plant hormone or animal hormone?
Auxin is a hormone that is found solely in plants.
When the auxin of a plant shoot is cut off does it grow back in?
Yes, when the auxin of a plant shoot is cut off, the plant will typically produce more auxin in an effort to promote growth and regeneration. This process helps the plant to develop new shoots and continue to grow.
The chemical that promotes phototropism is?
Auxin is the chemical that promotes phototropism in plants. Auxin is produced at the tips of plant stems and helps cells elongate, causing the plant to bend towards a light source.
How do plant hormones control the growth of roots and shoots?
Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
What is an auxin?
An auxin is a class of plant growth substance which plays an essential role in coordination of many growth and behavioural processes in the life cycle of a plant.
What term describes the direction of auxin transport in a plant?
Polar transport describes the direction of auxin transport in a plant. Auxin is moved from the shoot apex towards the roots in a polar manner, which helps regulate various plant processes such as growth and development.
What is the plant hormone that causes the plant to move towards the light?
Auxin
Does auxin builds up on the lit side of a plant shoot?
No, auxin does not build up on the lit side of a plant shoot. Instead, auxin is redistributed to the shaded side, promoting cell elongation there. This differential distribution causes the plant to bend towards the light, a phenomenon known as phototropism. Thus, the accumulation of auxin occurs on the side opposite to the light source.
What do auxin's control?
Auxin is a plant hormone that is involved in many signal processes. It is most commonly talked about in apical dominance
What effects does auxin have on plants?
auxin plays an important role in the growth of meristemetic tissue so as to increase the height of plant.
Are Auxin's used to make corn and wheat grow taller?
Yes because, Auxin is a plant hormone produced in a stem tip that promotes cell elongation. Then Auxin moves to the darker side of the plant causing the cells there to grow larger than the corresponding cells on the lighter side of the plant.
Phototropism in plants is mediated by what plant growth substance?
auxin
