Curated OER
Plant Hormones
Learners identify different plant hormones and explain their function in plant development. For this biology lesson, students investigate how IAA affect root growth. They study the history of auxin discovery.

Auxin: Indole-3-Acetic Acid (AAA), A Hormone with Diverse Effects: Synthesis and Applications
Learners synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. In this biochemistry activity, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.
