Nitrogen-Fixing Bacteria in Root Nodules of Leguminous Plants
Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.
Curated OER
Teaching Biology Through Problem-based Activities
Students plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.
