Lichens: Symbiotic Associations — NEET Biology
🔥 Predicted for NEET 2027Lichens: Lichens are symbiotic associations i.e. mutually useful associations, between algae and fungi. The algal component is known as phycobiont and fungal component as mycobiont. Most members of ascomycetes and basidiomycetes form lichens. The lichens are able to thrive in hostile environments like bare rock surfaces. The fungal partner provide shelter and absorb mineral nutrients and water for its partner. So there is their association that if one saw a lichen in nature one would never imagine that they had two different organisms within them. Lichens are very good pollution indicators - they do not grow in polluted areas.
