[8] Haustorium (pl. haustoria) – a root-like structure which allows the fungal partner to extract nutrients from its photosynthetic partner(s). [9] Lichen morphology – a lichen's external appearance and structures are very different than those of its individual partners. [10] Ascocarp – the fruiting body of a lichen, which contains the ...
English: This is a cross section of lichen, which is an organism in a symbiotic relationship between green algae and fungus. 1. Thick layers of hyphae, called the cortex 2. Green algae 3. Loosely packed hyphae 4. Anchoring hyphae called rhizines. Lichen is an organism that is composed of two separate organisms living in a symbiotic relationship.
Lichenometry relies upon the fact that the maximum diameter of the largest thallus of an epilithic lichen growing on a substrate is directly proportional to the time from first exposure of the area to the environment as seen in studies by Roland Beschel [24] in 1950 and is especially useful in areas exposed for less than 1000 years. Growth is ...
A foliose lichen is a lichen with flat, leaf-like lobes, which are generally not firmly bonded to the substrate on which it grows. It is one of the three most common growth forms of lichens. It typically has distinct upper and lower surfaces, each of which is usually covered with a cortex ; some, however, lack a lower cortex.
Lichen morphology describes the external appearance and structures of a lichen. These can vary considerably from species to species. These can vary considerably from species to species. Lichen growth forms are used to group lichens by "vegetative" thallus types, and forms of "non-vegetative" reproductive parts.
A lichen (/ ˈ l aɪ k ən / LIE-kən, UK also / ˈ l ɪ tʃ ən / LI-chən) is a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungi species, along with yeasts and bacteria [1] [2] embedded in the cortex or "skin", in a mutualistic relationship.
