Curated OER
Plant Growth
Examine the growth regions and tissues in plants. The structures and specialized areas of roots, stems, and shoots are defined and supported with diagrams and pictures. Your class will also learn the details of specific growth hormones.

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

Auxin: Indole-3-Acetic Acid
Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Science: A-maze-ing Plants
Students discover how light helps plants to grow. By placing a plant inside a box cut into a maze, they observe how the plant finds its way through the maze to the light source.
