auxin plays an important role in the growth of meristemetic tissue so as to increase the height of plant.
The effect of auxin on root growth is called root initiation or root elongation. Auxin promotes cell division and cell elongation in the root, leading to increased root growth.
slow cell growth
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.
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.

For the tissue culture/callus culture of Alstonia scholaris MS media supplemented with a balanced concentrations of 2,4-D(auxin) and FAP(cytokinin) can be used.The concentrations of auxin/cytokinin are*****mg/l [(kumarsumit90@gmail.com :) ;)]

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.
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 hormone
Phototropism is the biological process for auxin's.
SCI1, the first member of the tissue-specific inhibitors of CDK (TIC) class, is probably connected to the auxin signaling pathway.
