An organism that consists of a fungus and an alga living together in a symbiotic relationship. The alga supplies nutrients by photosynthesis, while the fungus shades the alga from excessive sunlight and supplies water by absorbing water vapor from the air. Lichens often live on rocks and tree ba...
Lichens are defined as a symbiotic relationship between filamentous fungi, photosynthesis capable organism (algae and/or cyanobacteria), and bacterial community. Such a complex symbiotic system with a wide diversity suggests the existence of molecules that are used as a way to induce such symbiosis ...
Lichens, symbiotic association between a fungus and one/more photosynthetic partners (algae/cyanobacteria), are prolific producers of structurally diverse secondary metabolites that play essential roles in organism survival, defense and ecological interactions [1,2,3]. Among the approximately 1000 lichen m...
Lichens are not single organisms, rather they are a symbiotic relationship between a fungus and an algae or cyanobacteria. The relationship works because each element helps the other. The fungi in lichens need sugars or carbohydrates as a food source and they g...
algae for food and in return provide a shady, moist, vitamin-rich environment, so sci- entists classify lichens based on their associated fungal species. Whether the fungi were harvesting algae or cyanobacteria, the symbiotic modus operandi of the lichens proved to be the same. Perhaps Trevor ...
Background: Lichens present a complex symbiotic relationship between a filamentous fungus, photoautotrophic partner (algae or cyanobacteria), and bacterial community. The Objective of the Study. This study aimed at investigating the chemical composition and cytotoxic, antioxidant, and antimicrobial activities...
Lichens on trees are a unique organism because they are actually a symbiotic relationship between two organisms — fungus and algae. The fungus grows on the tree and can collect moisture, which the algae needs. ... Lichen on tree bark is completely harmless to the tree itself. Why is ...

These are not single individual plants; each one is a symbiotic combination of an alga and a fungus. The algae capture the sun's energy by photosynthesis and store it in organic molecules. The fungi absorb moisture and mineral salts from the rocks, passing these on in waste products that ...
relationship where two species live together and both benefit. In this instance, the algae—or specializedblue-green algaecalled cyanobacteria—provide food and the fungi wraps around it creating a shelter. "The question of when lichens evolved and how many times fungi evolved the ability to form...
