Question

• A. It is an association of fungus and higher plants.
• B. It is association of algae and fungi.
• C. It is association of algae with higher plants.
• D. All of the above.

Answer 1

The correct option is A It is an association of fungus and higher plants.

Mycorrhizas are symbiotic associations essential for one or both partners, between a fungus (specialised for life in soils and plants) and a root (or other substrate-contacting organ) of a living plant, that is primarily responsible for nutrient transfer. Mycorrhizas occur in a specialised plant organ where intimate contact results from synchronised plant-fungus development. Mycorrhizal fungi are a major component of the soil microflora in many ecosystems, but usually have limited saprophytic abilities. They are considered to have many important roles in natural and managed ecosystems.

Thus, the correct answer is option A.
