photohomerone
true
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.
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.
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.
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.

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.

Plants rich in auxin include willow trees, soybeans, corn, peas, and sunflowers. Auxin is a plant hormone that regulates various aspects of plant growth and development, such as promoting cell elongation, root initiation, and apical dominance.
