What is the term for a symbiotic association between a fungus and a photosynthetic partner, such as a green alga or cyanobacterium?
A. Mycorrhiza
B. Lichen✓ Correct Answer
C. Rhizobium
D. Endophyte
💡 Solution & Explanation
Lichens represent a classic mutualistic symbiosis involving a fungal partner, known as the mycobiont, and a photosynthetic partner, known as the phycobiont. Mycorrhiza refers to the mutualistic association between fungi and plant roots, whereas Rhizobium forms symbiotic root nodules with legumes for nitrogen fixation. Lichens are exceptionally sensitive environmental indicators and serve as natural bio-monitors for sulfur dioxide air pollution.
