Chapter 37.3, Problem 1LO
Summary Introduction
To explain: The significance of nitrogen-fixing bacteria for plant nutrition.
Introduction: The plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The plant nutrients are defined as the chemical elements that are important for the nourishment of the health of a plant. There are two types of nutrients such as macronutrients and micronutrients that are obtained by the plant from their growing medium.

There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic) and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What is the advantage of using legumes as a cover crop in agricultural systems? A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen. This is a major problem for free-living aerobic species such as cyanobacteria and species of the genera Azotobacter and Beiigrinckia. Describe two ways the bacteria can overcome to levels of oxygen in their cells.arrow_forward

First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop.
