Question

Name an auxin which is both natural and synthetic.

Answer 1

Auxin:

1. Auxin is an important plant hormone responsible for the growth and development of a plant by promoting cell elongation.
2. Indole-3-acetic acid or IAA is an auxin that occurs naturally and can also be artificially synthesized.

Hence, an auxin that is both natural and synthetic is indole-3-acetic acid.
