Question

write any four functions of auxin in plant

Answer 1

Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotescell elongation.

Answer 2

Auxins are a kind of plant hormone with morphogen-like characteristics. Auxins play an important role in the synchronization of a variety of growth factors.

Some of its functions are;

1. When auxin comes into touch with a plant cell, it alters the expression of genes significantly, with numerous genes being upregulated or down-regulated. It is Auxin's molecular mechanism.
2. Auxin is required for cell development at the cellular level, controlling both cell proliferation and cell growth. Plant cell development and division result in tissue expansion, while specialized tissue growth culminates in the production of plant organs.
3. Auxins increase stem elongation while inhibiting lateral bud development (maintains apical dominance). They form in the stem, buds, and root tips. Indole Acetic Acid is one example (IA). Auxin is a plant hormone that stimulates cell elongation and is generated in the stem tip.
4. Auxins are essential for organ development, but they are also required for plant growth.
