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.

2025年2月26日 · lichen, any of about 15,000 species of plantlike organisms that consist of a symbiotic association of algae (usually green) or cyanobacteria and fungi (mostly ascomycetes and basidiomycetes). Lichens are found worldwide …

2023年2月11日 · A lichen is a symbiotic relationship between a fungus and a photosynthetic partner (algae, cyanobacteria, or both). Lichens grow all over the world and can even survive exposure to space. They take many forms and are classified according to the type of fungi they contain as well as their shape.

Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies. The alga can be either a green alga or a blue-green alga, otherwise known as cyanobacteria.

The meaning of LICHEN is any of numerous complex plantlike organisms made up of an alga or a cyanobacterium and a fungus growing in symbiotic association on a solid surface (such as on a rock or the bark of trees).

2019年4月24日 · What is a lichen? Lichens are actually made up of two or more different organisms. These exist in a mutually beneficial relationship called symbiosis. So you can think of lichen as a successful partnership, between: a fungus; an algae and/or cyanobacteria. The fungus element requires carbohydrate as a food source.

2024年5月29日 · But the lichen story doesn’t end there. Recent discoveries have revealed a surprising level of complexity. Beyond the main fungal partner and single-celled algae, lichens often harbor a diverse community of bacteria, other fungi, and even tiny multicellular animals like tardigrades and nematodes.
