Cell elongation is defined as the lengthening of a cell during differentiation of a cell. It takes place during growth of an organism or during movement in mature plants.
In plants, it is primarily regulated by light and plant hormones like auxin.
Auxin modifies the structure of the cell wall which helps the cell to elongate.
