WebAbstract. Lichens are dual organisms formed from a symbiotic association of a fungus, the mycobiont, and an alga and/or cyanobacterium, the photobiont, in which numerous photosynthetic cells are intertwined in a matrix of fungal hyphae.

WebA lichen looks like a single organism, but it is actually a symbiotic relationship between different organisms.
