Question

Where are auxins synthesised in plants? Mention any two of their functions.

Answer 1

Auxins are plant growth promoters, generally produced by the growing apex of stem and root of the plants, from where they migrate to the regions of their action. Auxins have a very important role in coordination of many growth and behavioral processes in the plant's life cycle and are essential for plant body development. Functions of Auxins:

1) Elongation of shoot and root tips behind the apical meristem

2) Delaying leaf abscission (fall of leaves)

3) Apical Dominance (inhibit growth of lateral/ axillary buds)
