How auxin controls phototropism?
Auxin is a plant hormone that regulates phototropism by promoting cell elongation on the side of the plant that is away from light. When a plant receives light from one direction, auxin redistributes to the shaded side, causing those cells to elongate more than those on the illuminated side. This differential growth results in the plant bending toward the light source. Thus, auxin plays a crucial role in helping plants optimize light exposure for photosynthesis.
What are effects of auxin in geotropism?
Auxin promotes geotropism by redistributing through the plant in response to gravity. In roots, auxin accumulates on the lower side causing elongation of cells and downward growth, while in shoots, it accumulates on the upper side causing inhibition of elongation and upward growth. This differential distribution of auxin helps plants respond to gravity and grow in the right direction.
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.
What is the plant hormone that causes the plant to move towards the light?
Auxin
What meant by phototropic movement?
When concluded that auxin accumulated on the side of the plant away from the light. When auxin flowed in this direction, the cells of the apical meristem elongated on that side and caused the plant to bend toward the light as growth continued.
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.

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 is the plant hormone that causes the plant to move towards the light?
Auxin
What is the physical basis of the phototropic response?
Phototropic response in plants is based on the redistribution of the plant hormone auxin, which promotes cell elongation on the shaded side of the plant, causing it to bend towards the light source. This redistribution is mediated by photoreceptors called phototropins, which sense the direction of light and trigger the movement of auxin to induce the plant's growth towards light.
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.
