Answer to Question 1

Root hairs grow. They release root exudates (flavonoids, sugars, amino acids, etc.), which attract specific rhizobia to the root. The rhizobia attach to the root hair surface. The root hair curls, entrapping the Rhizobium. The rhizobia digest the cell wall and form an infection thread into the center of the root. Within the thread, the bacteria divide and increase in numbers. The rhizobia induce division of the root cells. A nodule is formed from the protrusion of the root cells from the surface.Within the individual root cells, the bacteria become devoid of a cell wall and become bacteroids, which develop the nitrogenase enzyme and fix atmospheric nitrogen.
