Verified step by step guidance1
Understand the concept of symbiotic relationships: Symbiosis is a close and long-term biological interaction between two different biological organisms. It can be mutualistic, commensalistic, or parasitic.
Identify the types of symbiotic relationships: In this context, we are looking at mutualistic relationships, where both organisms benefit from the association.
Define Mycorrhiza: Mycorrhiza refers to a mutualistic association between the roots of a plant and a fungus. In this relationship, the fungus enhances water and nutrient absorption for the plant, while the plant provides carbohydrates and other organic compounds to the fungus.
Differentiate Mycorrhiza from other associations: Saprophytism involves fungi decomposing dead organic matter, not forming a mutualistic relationship with living plants. Parasitism involves one organism benefiting at the expense of another. Lichen is a mutualistic relationship between a fungus and an alga or cyanobacterium, not specifically with plant roots.
Conclude that Mycorrhiza is the beneficial association: Based on the definitions and characteristics, Mycorrhiza is the correct answer as it describes a beneficial mutualistic relationship between plant roots and fungi.
