Describe the process of development of root nodules in the leguminous plants. Name the oxygen scavenger molecule present in root nodules?
Legumes are the seeds of the plant and when these seeds are dried out, they are used for the pulses. These are the edible seed pods that include lentils, peas, chickpea, gram, etc. Root nodules are the organs developed by the main plant, mostly legumes, in which the symbiotic microorganism reduces the nitrogen to ammonia. The root nodules in legume plants are produced due to the bacteria Rhizobium. The purpose is to fix the nitrogen and enrich the soil with fertilizers. It is basically the connection between the rhizobium and plant Formation of root nodules in a leguminous plant: (1) The root nodule is formed when a root hair of a leguminous plant comes in contact with Rhizobium. (2) Bacteria occupy and increase with the root hair. (3) To unfurl the bacteria, Bacteroides enlarge to become membrane (4) Infection thrust made of the plasma membrane is formed by the host that distinguishes the infected cell from the tissue. (5) Cell division is gorged in the infected tissue that directs more bacteria to enter the newly formed cells. (b) Leghaemoglobin (Lb) is the oxygen scavenger found in root nodules of legume plants.
