Isolation of Synthetic Chemicals from Plant Leaves
Young scholars isolate and identify a dye, which represents a synthetic pesticide, from plants.
Curated OER
Molecular Evolution in Plants
Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
