Detailed explanation-1: -The plant hormone auxin is well known to stimulate cell elongation via increasing wall extensibility. Auxin participates in the regulation of cell wall properties by inducing wall loosening. Here, we review what is known on cell wall property regulation by auxin.

Detailed explanation-2: -Auxin promotes cell division and meristem maintenance and also plays an important role in the establishment of cellular patterning. Plant development thus integrates the regulation of cell proliferation and growth with further cell expansion and differentiation.

Detailed explanation-3: -IAA is produced by cells in the shoot tip and diffuses down the stem, accumulating in the cells on the shaded side of the shoot. IAA stimulates cell elongation in these shaded cells, causing them to elongate comparatively more than the cells that are illuminated by the light source.

Detailed explanation-4: -An example is IAA (Indole Acetic Acid).-It is a type of plant hormone which produces in the tip of the stem and promotes cell elongation.-Auxin migrates to the darker side of the plant and there they enhance the growth of the cell in comparison to the lighter side of the plant.
