A lichen is an organism that results from a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The fungus benefits from the constant supply of food produced by the photosynthesizer.

What type of relationship is between the algae and fungus?
A lichen is not a single organism; it is a stable symbiotic association between a fungus and algae and/or cyanobacteria. Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyanobacteria, that are photosynthetic.
How do algae and fungi benefit each other?
Symbiotic relationship between algae and fungi is called Lichen. Algae and fungi get benefit from each other as algae provide food to fungi and fungi provide water to algae. This way they both get nutrition for survival.
What is mutualistic fungi?
When both members of the association benefit, the symbiotic relationship is called mutualistic. Fungi form mutualistic associations with many types of organisms, including cyanobacteria, algae, plants, and animals.
What is mutualism relationship?
Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How do fungi and algae benefit from each other in their relationship in lichens?
In some ways, the symbiotic relationship between lichens and algae seems like a mutualism (a relationship in which both organisms benefit). The fungus can obtain photosynthates from the algae or cyanobacterium and the algae or cyanobacterium can grow in a drier environment than it could otherwise tolerate.
Is algae a cyanobacteria?
Cyanobacteria are sometimes considered algae, but they are actually bacteria (prokaryotic), where the term “algae” is now reserved for eukaryotic organisms. They also derive their energy through photosynthesis, but lack a nucleus or membrane bound organelles, like chloroplasts.
How do fungi and algae benefit each other in their symbiotic relationship as lichen?
Fungi and algae share their food among each other. The algae or the cyanobacteria benefit their fungal partner by producing organic carbon compounds through photosynthesis. And the relationship is called symbiotic relationship.
How does lichen demonstrate mutualism?
Lichens are not a single organism, but, rather, an example of a mutualism in which a fungus (usually a member of the Ascomycota or Basidiomycota phyla) lives in close contact with a photosynthetic organism (a eukaryotic alga or a prokaryotic cyanobacterium).
What is the term used to describe the mutualistic combination of plants and fungus if the fungus is able to penetrate the plant cell walls?
mycorrhizae, mycorrhiza or mycorrhizas) is a mutual symbiotic association between a fungus and a plant.
How does mutualistic fungus obtain nutrients?
Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic; they rely solely on carbon fixed by other organisms for their metabolism and nutrition.
Which of the following describe mutualism?
Mutualism is defined as an interaction between individuals of different species that results in positive (beneficial) effects on per capita reproduction and/or survival of the interacting populations.
What do you mean by mutualism explain in brief?
mutualism, association between organisms of two different species in which each benefits. Mutualistic arrangements are most likely to develop between organisms with widely different living requirements.
What is the role of algae and fungi in lichens Class 7?
In lichens, algae is an autotroph while fungus is an saprophyte. Water and minerals are supplied by the fungus to algae and using them algae makes food with the process of photosynthesis and supplies food to fungus. Hence, both "mutually benefit" each other.
What name is given to the relationship between an alga and fungus in lichens Class 7?
Relationship between alga and fungus in lichens is a form of symbiosis known as mutualism. Both are benefited from this relationship.
