Question

Is rhizobium bacteria change its shape during nitrogen fixation?

Answer 1

Legume nitrogen fixation starts with the formation of a nodule. A common soil bacterium, Rhizobium, invades the root and multiplies within the cortex cells. The plant supplies all the necessary nutrients and energy for the bacteria.

Nodules on many perennial legumes such as alfalfa and clover are finger-like in shape.

Hope this helps ☺️☺️☺️☺️

Answer 2

$\huge\mathfrak\red{HeyA..!}$

Rhizobium forms a symbiotic relationship with certain plants such as legumes, fixing nitrogen from the air into ammonia, which acts as a natural fertilizer for the plants. ... This research involves the genetic mapping of various rhizobial species with their respective symbiotic plant species, like alfalfa or soybean.
