Assertion and Reason_Monera
Numerical
Assertion:The nitrogen-fixing bacteria in leguminous plant nodules live as symbionts.
Reason Leg-haemoglobinsynthesized by lequminous plants protect bacteria.
Correct Answer: A
Explanation:
Rhizobium form a symbiotic association with roots of leguminous plants producing root nodules. These bacteria reside inside the nodules and reduce atmospheric nitrogen (N2) to ammonia. The fixed nitrogen is taken up by plant. In return the plant provides nutrients both and protection to bacteria.
