Lichens info Information about lichens 1.
Lichens are in fact a symbiotic lifeform between a fungus and a alga.
For a long time lichens even were concidered to be a seperate taxonomic group. Until in the 18th century lichens were even concidered to be mosses. A symbiosis is a lifeform where all the partners have profit of each other. Often the partners get so dependant on each other, that they are not able to live separately any more. In the case of the lichens, the fungus delivers water and minerals to the alga, while the alga takes care of the fotosynthesis ans supplies suchars to the fungus.
