Chapter 31, Problem 1CHI

Why might vascular plants have developed relationships with so many types of microorganisms? These molecular-level interactions show many similarities when microbe-plant and microbe-human interactions are considered. What does this suggest concerning possible common evolutionary relationships?

Summary Introduction

To determine: The possible reason for the development of relationships with many types of microorganisms by the vascular plants.

Introduction: Aquatic plants have evolved into terrestrial organisms with the help of soil microorganisms. This establishes a plant-microbe relationship. The interaction between plants and microbes may be beneficial for both or for only the microbes.

Explanation of Solution

Vascular plants are the plants that can absorb water through roots and then supply it to their different parts. Vascular plants have developed a relationship with different types of microorganisms as a means of survival. This association of plants with different types of microbes ensures that if one species of microbes perishes, the other microbial species is available to increase the uptake of nutrients and water by the plant.

Summary Introduction

To determine: The common evolutionary relationships suggested by the similarities in molecular level interactions in microbe-plant and microbe-human interactions.

Introduction: Aquatic plants have evolved into terrestrial organisms with the help of soil microorganisms. This establishes a plant-microbe relationship. The interaction between plants and microbes may be beneficial for both or for only the microbes.

Explanation of Solution

The molecular level plant-microbe and human-microbe interactions show some similarities. This similarity suggests a convergent evolution of these microbes, which means that different microbial species evolved from different ancestors, but they still shared common traits due to similar selection pressures.

One of the most widely known symbioses between microorganisms and plants is that of rhizobia and legumes. The basis of this mutualistic, symbiotic relationship can be described by which of the following statements?   Actually, all of these are accurate descriptions of the symbiosis between rhizobia and plants. Rhizobia help the plants expand access to minerals in the soil while the plant protects the rhizobia from predators and viruses. The rhizobia will conduct photosynthesis which allow the plants to access carbon without having to deplete their own energy to do carbon fixation. The rhizobia fix nitrogen for the plant while the plant fixes carbon which it shares with the rhizobia. The rhizobia will produce oxygen which will help the soil to maintain oxygenation and thus avoid pathogens.
The roots of legumes, such as peas and beans, have special nodules that are home to large numbers of bacteria. What benefit do these bacteria provide to the plant? What do they receive in exchange?
How do plants benefit from symbiotic associations with bacteria? With fungi?
