Rhizobium Bacteria live in the root nodules of legumes

today we looked at the root nodules in a legume plant.  These plants have a symbiotic relationship with a nitrogen fixing bacteria called rhizobium.  Not all plants have these nodules. Legumes are plants that make pods like soybean, clover, alfalfa, kidney beans, peas.

We tested several plants for the presence of nodules and to discover which ones are, in fact, legumes.  We also observed some insects found on some of the specimens.
