The growth of a plant cell may be separated schematically into the following stages: cell division, plasmatic growth and cell elongation. The definite proof that the growth of plant cells is regulated by plant hormones has first been found for the process of cell elongation. The termauxins is used to designate these hormones. The function of auxins in plants is not limited to cell elongation. Botanical investigations have shown that they also play a role in phototropism and geotropism, that they stimulate root development, induce cambial growth and prevent premature outgrowth of axillary buds. Auxins therefore regulate plant growth in many ways.
