Lichens are symbiotic associations of mutualism between fungi and algae. Most lichen-forming fungi are ascomycetes (98%), the remainder being basidiomycetes. The algae involved in this association are chlorophytes and cyanobacteria. The fungi of this association are called mycobionte and the algae, photobionte, since it is the photosynthetic organism of the association.
The dual nature of lichen is easily demonstrated by the separate cultivation of its components. In the association, the fungi take different forms from those they had when isolated, most of the body of the lichen is formed by the fungus.
Lichen is the term for the symbiotic association between fungi and cyanobacteria. Lichens are harmonious relationship of mutualism among growths and green growth. Most lichen-shaping organisms are ascomycetes (98%), the rest of basidiomycetes. The green growth engaged with this affiliation are chlorophytes and cyanobacteria. The parasites of this affiliation are called mycobionte and the green growth, photobionte, since it is the photosynthetic living being of the affiliation. The double idea of lichen is effectively shown by the different development of its parts. In the affiliation, the growths take various structures from those they had when secluded, the vast majority of the body of the lichen is framed by the organism.
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent). ... When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration.
