auxin
Obie Ondricka
Auxins promote cell growth by increasing cell elongation through the activation of proton pumps in the cell membrane, which leads to an influx of protons and an acidification of the cell wall. This acidification activates enzymes that break down the cell wall, allowing for increased cell expansion and growth. Additionally, auxins stimulate the synthesis of specific proteins that are involved in cell expansion.

Why does rooting powder help cuttings grow?
The powder helps plant to grow because it contains plant hormones called auxins. Auxins cause the new cells produces by the base of the shoot meristem to develop into roots.
How do auxins cause a plant to grow toward a light source?
Auxins accumulate on the shaded side of the stem, promoting cell elongation. This causes the cells on the shaded side to elongate more, bending the stem towards the light. This phenomenon is known as phototropism.
What hormone cause photoTropism?
auxins
What does geotropism cause a plants roots to do?
the auxins in the plant and the gravity
How do auxins cause hydrotropism?
Roots show positive hydrotropism and grow in the direction of water. This tropism causes problems in many cities where tree roots grow toward the drain pipes, and grow into the cracks, and plug up the drains. Hydrotropism causes plants to bend or turn toward water.

How do auxins plants effect plant cells?
bootyThe auxins plants do deform the plant cells.
How do auxins affect plant cells?
Auxins regulate cell elongation and division in plants by promoting cell growth in response to specific environmental cues. They can also influence root development, apical dominance, and tropic responses like phototropism and gravitropism. Auxins work by triggering changes in gene expression and protein activities within plant cells, ultimately leading to various growth responses.
Explain how auxins could cause hydrotropism?
Auxins are plant hormones that promote cell elongation and growth. In hydrotropism, when roots grow towards water, auxins are redistributed within the root, leading to differential growth on the side of the root facing the water source. This differential growth causes the root to bend and grow towards the water, helping the plant locate and access water.

What auxin is not stable in light?
auxins are not stable in light because it will degenerate the hormones.so,when light touches at one side of the coleoptile,auxins will move to the other side (less sunlight).this makes the shoot grow faster at the side which have more auxins and slower at the place where there are less auxins and this makes the shoot bend towards the light source =P
What happens to auxin's when they are exposed to light?
When auxins are exposed to light, they tend to move away from it, which is known as phototropism. This movement helps plants to grow towards light sources by elongating cells on the shaded side of the plant.
What lets the plant grow up towards the light?
The plant hormone auxin, produced in the tip of the plant shoot, helps the plant to grow towards the light by promoting cell elongation on the shaded side of the stem. This causes the stem to bend towards the light source, a response known as phototropism.
Why are auxins in weed killers?
Auxins are plant hormones that regulate growth, and in weed killers, synthetic auxins are used to disrupt the normal growth patterns of plants. By applying auxins in high concentrations, the weed killer can cause uncontrolled growth, leading to symptoms like twisting, bending, and abnormal growth that eventually kills the plant.
