Question

An organism used as a bio-fertilizer for raising soybean crop is:

A

Azospirillum

B

Rhizobium

C

Nostoc

D

Azotobacter

Step-by-Step Solution

Rhizobium bacteria form symbiotic associations with the roots of leguminous plants (like soybean) to form nodules. These bacteria fix atmospheric nitrogen into organic forms, which are used by the plant as nutrients . In contrast, Azospirillum and Azotobacter are free-living nitrogen-fixing bacteria found in the soil , and Nostoc is a free-living or symbiotic cyanobacterium .

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Microbes in Human Welfare. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
