Detailed explanation-1: -Lichens are symbiotic associations between fungi (mycobionts, commonly Ascomycetes ) and photosynthetic partners (photobionts ) which can be green algae (commonly Trebouxia spp.) or diazotrophic cyanobacteria (commonly Nostoc spp.). These mycobiont-photobiont symbioses are regarded as mutualistic .

Detailed explanation-2: -Lichens are commonly recognized as a symbiotic association of a fungus and a chlorophyll containing partner, either green algae or cyanobacteria, or both. The fungus provides a suitable habitat for the partner, which provides photosynthetically fixed carbon as energy source for the system.

Detailed explanation-3: -A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria. Some lichens are formed of three or more partners. The body of a lichen consists of fungal filaments (hyphae) surrounding cells of green algae and/or blue-green cyanobacteria.

Detailed explanation-4: -In lichens, the interaction between algae and fungi is a symbiotic relationship. Algae feed fungi that lack chlorophyll pigments. Fungi, on the other hand, help algae by providing protection and aiding in water absorption. No one is injured in this form of connection, and both parties benefit from it.

Detailed explanation-5: -Symbiosis in lichens is the mutualistic relationship of algae living among filaments of a fungus. The fungus benefits from the algae or cyanobacteria because they produce food by photosynthesis. The fungus provides water, nutrients and shelter for the algae.
