@trregeagle The life of the bacteria (called "#rhizobia" (="those who live in the root")) in the #RootNodules is really weird. They are totally isolated from oxygen because the nitrogen fixation only works in absence of oxygen. The plant feeds the rhizobia completely. It's like a golden cage. But as with the golden cage, there is a downside. After a while, the plant simply disassembles the root nodules and digests the bacteria. Although often considered as #symbiosis, it's actually #farming.

@trregeagle There are so many cool aspects about #peanuts. Peanuts belong to the #legume family (#Fabaceae) like peas, beans, chickpeas, or lupins fava beans.
As it is typical for legumes, the plants develop a close relationship with certain soil bacteria, which grow into the legume root and produce #RootNodules. Only in these nodules, these #bacteria start to fix nitrogen, which is then stred as #protein in the seeds of the #plant. That's why legumes are so valuable as #food.
