Question

18. The root nodules in legume plants are produced due to infection of bacteria Rhizobium. This free-living soil bacteria usually grows near the roots of the legumes. It fixes nitrogen only when it enters into the root and is present inside root- nodules. What is the function of root nodules in leguminous plants? O A) Store food B) Provide extra strength O ) Perform photosynthesis D) Give shelter to bacteria​

Answer 1

Answer:

Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen.

Answer 2

Answer:

A. Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen.
