Question

describe the steps in the formation of root nodules in legume

Answer 1

Answer: Steps in Nodule Formation Nodule formation involves a sequence of multiple interactions between Rhizobium and roots of the host plant. Principal stages in the nodule formation are: (i) Rhizobia multiply and colonise the surroundings of roots and get attached to epidermal and root hair cells

Answer 2

The Rhizobium bacteria divide and form colonies. ... The bacteria get modified into rod-shaped bacteroides. 4) As a result, the cells in the cortex and pericycle undergo division, leading to the formation of root nodules. 5) The nodules finally get connected with the vascular tissues of the roots for nutrient exchange.
