How do you feel about root nodules in legumes?

I think they’re very neat despite them looking kinda weird. They provide a home for symbiotic nitrogen-fixing bacteria called rhizobia.

Rhizoba captures nitrogen gas from the atmosphere and converts it into ammonia which is then used to make amino acids and nucleotides.

The root nodules are sometimes taken advantage of and in some traditional farming pratices are used in a rotating crop pattern to put nitrogen back into the soil and fertilize it. Which I think is very neat!
