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 else can I help you with?
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 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.
The effect of auxin depends on the target tissue?
true
What effect does auxin on plant roots?
slow cell growth
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.

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.
Is auxin a plant hormone or animal hormone?
Auxin is a hormone that is found solely in plants.
What effect does auxin on plant roots?
slow cell growth
The effect of auxin depends on the target tissue?
true
