We would expect the greatest difference in plant health between two groups of plants of the same species, one group with mycorrhizae and one group without mycorrhizae, in an environment ________.

Question

Quizplus · Accepted Answer

Mycorrhizae are symbiotic associations between fungi and plant roots that enhance nutrient uptake, particularly for mineral nutrients like phosphorus. Therefore, the greatest difference in plant health between two groups of plants, one with and one without mycorrhizae, would be seen in an environment where the soil is relatively deficient in mineral nutrients. The presence of nitrogen-fixing bacteria, poor drainage, or proximity to water would not necessarily have as great an impact on plant health in the context of mycorrhizal associations.
