Question

Mycorrhiza is a symbiotic

• A. Association of algae and fungi
• B. Association of fungi and higher plants
• C. Association of lichens and fungi
• D. Association of lichens and algae

Answer 1

The correct option is B Association of fungi and higher plants

Mycorrhiza is a symbiotic association between fungus and roots of higher plants like Pinus, for absorption of water and minerals.

Plant roots alone may be incapable of taking up phosphate ions that are demineralized in soils with a basic pH. The mycelium of the mycorrhizal fungus can, however, access these phosphorus sources, and make them available to the plants they colonize.
