Do bean roots make nitrogen by themselves? Legume roots host rhizobia; the partnership fixes nitrogen, the plant does not do it alone. The number to keep beside that choice is 1886. Hellriegel’s work around 1886 showed nodules, not the leaf, were the seat of that fixation.
Legume roots host rhizobia; the partnership fixes nitrogen, the plant does not do it alone. The figure 1886 belongs in the answer because Hellriegel’s work around 1886 showed nodules, not the leaf, were the seat of that fixation. This page explains a classification or public-health fact. It does not diagnose an illness or write a treatment plan.

Legume roots host rhizobia; the partnership fixes nitrogen, the plant does not do it alone. Hold the figure 1886 beside that sentence, then use the atlas link for the longer chapter. This lookup only settles the search decision named in the heading.
Hellriegel’s work around 1886 showed nodules, not the leaf, were the seat of that fixation. That is why 1886 is printed on this card rather than left as a vague “many”. Open the linked section if you need the map, not a personal instruction.
The wrong turn is to treat the opposite claim as the same fact. Legume roots host rhizobia; the partnership fixes nitrogen, the plant does not do it alone. This page explains a classification or public-health fact. It does not diagnose an illness or write a treatment plan.
After the decision, read the two linked atlas pages and stop. Hellriegel’s work around 1886 showed nodules, not the leaf, were the seat of that fixation. This page explains a classification or public-health fact. It does not diagnose an illness or write a treatment plan.
