The effect of auxin depends on the target tissue?
true
What may be a cause of root gravitropism?
Root gravitropism is mainly controlled by the hormone auxin. The differential distribution of auxin across the root due to gravity is a key factor in causing roots to grow downward. The auxin gradient results in differential cell elongation on the upper and lower sides of the root, leading to root bending towards gravity.
What is the effect of auxin on different parts of plants?
Auxin is a plant hormone that regulates growth and development by promoting cell elongation, particularly in stems and roots. In stems, auxin facilitates upward growth by concentrating on the side away from light, causing the plant to bend towards the light (phototropism). In roots, auxin influences downward growth and root development, but in higher concentrations, it can inhibit root elongation. Overall, auxin plays a crucial role in coordinating directional growth and responses to environmental stimuli.
What is the effect of auxin on shoots called?
The effect of auxin on shoots is known as phototropism. Auxin promotes cell elongation on the side of the shoot that is away from light, causing the shoot to bend toward the light source. This growth response allows the plant to maximize light exposure for photosynthesis. Additionally, auxin plays a role in apical dominance, where it inhibits lateral bud growth, directing energy toward the main shoot.
What does auxin on the plants roots?
Auxin is a plant hormone that plays a crucial role in root development and growth. It promotes cell elongation and is involved in the regulation of root gravitropism, allowing roots to grow downward in response to gravity. Additionally, auxin influences the formation of lateral roots, enhancing the plant's ability to absorb water and nutrients from the soil. Overall, auxin helps coordinate root growth and response to environmental stimuli.
What is the chemical produced growing in root tips?
Auxin hormone
What is the hormone for root?

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

Overall, auxin helps coordinate root growth and response to environmental stimuli.
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.
How Auxin stimulates root disk growth?
Auxin, a plant hormone, stimulates root disk growth by promoting cell elongation and division in the root meristem. It influences the distribution of other hormones, such as cytokinins and gibberellins, which further enhance growth processes. Additionally, auxin affects the activity of genes involved in cell wall loosening and expansion, allowing for increased root growth and development. This coordinated hormonal signaling leads to the efficient growth of root structures.
