Practice questions testing deep understanding of bacterial structure, reproduction, and economic importance.
Q1. A scientist places a few bacteria in a nutrient-rich petri dish. After just 12 hours, the dish is completely covered with millions of bacterial colonies. Explain the biological mechanism of reproduction that allows bacteria to multiply at such an incredibly rapid rate.
Q2. Assertion (A): In agriculture, farmers often add specific bacteria directly to the soil before planting crops. Reason (R): Certain free-living bacteria like Azotobacter, or symbiotic bacteria like Rhizobium, are required to fix atmospheric nitrogen into nitrates, which acts as a natural fertilizer for the crops.
