Give four major functions of auxins.

1.	Give four major functions of auxins.
Answer» Ans :- Cell Elongation:Auxins promote elongation growth in young stems and coleoptiles. Tropism – Responses to Stimulus of Light & Gravity:Auxin meditates the effect of light and gravity on plant growth. Apical Dominance:It is commonly observed that apical bud of many vascular plants is very active in growth and lateral buds remain inactive. Formation of Lateral Roots:Optimal auxin concentration in primaryrootinhibits elongation growth, but high level auxin levels stimulate initiation of lateral roots and adventitious roots. Delay in Leaf Abscission:The shedding of leaves, flowers and fruits from the living plant is known as abscission. Fruit Development:The auxin is involved in the regulation offruitdevelopment.
