auxin plays an important role in the growth of meristemetic tissue so as to increase the height of plant.
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.
It is Auxin produced in the stem apex.
If human body have hormones, same true with plants and this plant hormones called auxin. It is a substance naturally produced in actively growing parts of plants that regulate many aspects of plant growth and development.
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.
Auxin is a hormone that is found solely in plants.

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
