Auxin is a plant hormone that plays a crucial role in plant growth and development. Some of its main functions include:
Promoting cell division and elongation, which helps the plant grow taller and thicker
Regulating the development and growth of lateral buds, which helps the plant branch out and become more complex
Controlling the orientation of the plant's shoots and roots, which helps the plant absorb nutrients and anchor itself in the ground
Regulating the development of fruits and flowers, which helps the plant reproduce and spread its genetic material.
Overall, auxin plays a vital role in the plant's ability to grow, develop, and adapt to its environment.
