Description
Lichen, wood, old wood, parasite, symbiosis, forest, rocky, rocks, Lichenes, Lichens lat. Lichenes are complex organisms, composed of at least two members: mycobionta - fungus and photobionta - algae and / or cyanobacteria, united in a mutualistic symbiotic community. But there is also a current of scientists who claim that the relationship is essentially different, that the mycobiont holds photobionts captive. The main part, on which the shape and appearance of the lichen depends and which quantitatively predominates, is the fungus. The hyphae of the fungus are so densely intertwined, that they build a false tissue, the plectenchyma.The members of this symbiosis complement each other by:algae photobiont and / or cyanobacteria / blue-green algae perform photosynthesis, and cyanobacteria can also bind nitrogenfungus mycobiont from the group of ascomycetes lat. Ascomycetes or basidiomycetes lat. Basidiomycetes or deuteriomycetes lat. Deuteriomycetes with its hyphae provides mechanical protection to the whole system, from drying out, herbivores, ....The symbiosis of algae and fungi creates an organism with properties that neither other species have in common and which are so unusual that lichens are often called the `chaos of nature`.
