Which one of the following statements is correct?a)Legumes fix nitrog...
Explanation:
Legumes are a group of plants that are capable of fixing nitrogen from the atmosphere into a form that can be used by plants. This process is carried out by specialized bacteria that live in the root nodules of leguminous plants. The correct statement among the given options is option 'A', which states that legumes fix nitrogen only through the specialized bacteria that live in their roots.
How does nitrogen fixation occur in legumes?
Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) by bacteria. Leguminous plants have a symbiotic association with nitrogen-fixing bacteria called rhizobia, which live in their root nodules. The process of nitrogen fixation occurs as follows:
1. The rhizobia bacteria infect the root hairs of leguminous plants and cause the formation of root nodules.
2. Inside the nodules, the bacteria convert atmospheric nitrogen into ammonia through the process of nitrogen fixation.
3. The ammonia is then converted into amino acids and other nitrogen-containing compounds, which are used by the plant for growth and development.
4. In return, the plant provides the bacteria with a source of energy and carbon in the form of sugars and other organic compounds.
Why can't legumes fix nitrogen independently of the specialized bacteria that live in their roots?
Legumes do not have the ability to fix nitrogen independently because they lack the enzyme nitrogenase, which is required for nitrogen fixation. The rhizobia bacteria have this enzyme and are therefore able to convert atmospheric nitrogen into ammonia. Without the bacteria, legumes would not be able to fix nitrogen and would have to rely on external sources of nitrogen, such as fertilizers.
Conclusion:
In summary, legumes fix nitrogen through the symbiotic association with specialized bacteria called rhizobia, which live in their root nodules. This process is essential for the growth and development of legumes and allows them to thrive in nitrogen-poor soils.

The nitrogen-fixing ability of leguminous plants is not a property of the plants as such but results from infection of their roots by bacteria in the soil, infection leading to the formation of nodules. These organisms are Gram-negative motile rods that are classified in the genus Rhizobium.
