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.
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.
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.

Auxin is the chemical that promotes phototropism in plants. Auxin is produced at the tips of plant stems and helps cells elongate, causing the plant to bend towards a light source.
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.

Auxin were the first plant hormones discovered. Charles Darwin was one of the first pioneers and wrote a book called The Power of Movement in Plants - 1880
A growth hormone called auxin.

Phototropism is the biological process for auxin's.

Auxin is a hormone that is found solely in plants.
Plants have a hormone called auxin in them. When a plant is exposed to light and shade this hormone(auxin) reacts. For example: If light falls on the right hand side of the plant, the left hand side would be in the shade. This makes the auxin expand in the shaded area, causing the plant to grow towards the light.
