Verified step by step guidance1
Understand the role of mycorrhizal fungi: Mycorrhizal fungi form a symbiotic relationship with plant roots, enhancing the plant's ability to absorb water and essential nutrients, particularly phosphorus and nitrogen, from the soil.
Evaluate the options given: Consider each statement about mycorrhizal fungi and determine if it aligns with their known biological function.
Option analysis: Mycorrhizal fungi do not prey on nematodes, produce carbohydrates, prevent transposons, or live in leaves to produce toxins. These statements do not describe the primary function of mycorrhizal fungi.
Identify the correct function: The primary benefit of mycorrhizal fungi is their ability to assist plants in the absorption of essential nutrients, which is crucial for plant growth and health.
Conclude the reasoning: Based on the analysis, the correct answer is that mycorrhizal fungi assist plants in the absorption of essential nutrients, which is why they are added to soil when planting trees and other plants.
