Question

In the symbiotic relationship between a bacteria and leguminous plant, which of the following statements is true?

• A. Bacteria provide $N_2$ and the plant roots provide Carbon
• B. Roots provide $N{H}_4$ and bacteria provide Carbon
• C. Bacteria provide $N{H}_4$ and the roots provide Carbon
• D. Bacteria provide $N_2$ and the roots provide $N{H}_4$

Answer 1

The correct option is C

Bacteria provide $N{H}_4$ and the roots provide Carbon

In legumes and a few other plants, bacteria live in small growths on the roots called nodules. Within these nodules, nitrogen fixation is done by the bacteria, and the $N{H}_3$ they produce is absorbed by the plant. Nitrogen fixation by legumes is a partnership between a bacterium and a plant. During ammonification, bacteria provide $N{H}_4$ and roots provide carbon.
