auxin

Auxin is a plant hormone that plays a crucial role in coordinating growth and development. It influences processes like cell elongation, root formation, and the bending of plants toward light (phototropism). Auxin is produced mainly in the tips of shoots and roots and then transported throughout the plant, helping cells respond to environmental cues. By regulating where and how cells grow, auxin ensures plants develop properly and adapt to their surroundings. Its precise control over growth patterns makes it vital for plant health and development.
