Answer 1

A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species[1] in a mutualistic relationship.[2][3][4] Lichens have different properties from those of its component organisms. Lichens come in many colors, sizes, and forms and are sometimes plant-like, but lichens are not plants. Lichens may have tiny, leafless branches (fruticose), flat leaf-like structures (foliose), flakes that lie on the surface like peeling paint (crustose),[5] a powder-like appearance (leprose), or other growth forms.[6]
