What is an organism that is composed as both fungus and alga?
Lichens
Does only one organism benefits from a lichen?
No. The alga and the fungus that make up a particular lichen exist in a true symbiotic relationship where neither can exist without the other. Generally, the fungi absorb water that passes on to the algae to be used in photosynthesis to create a carbohydrate food for both. So both organisms benefit from the relationship.
What type of symbiosis exists between fungus and alga in a lichen?
The type of symbiosis that exists between fungus and alga in a lichen is mutualism. The fungus provides structure and protection for the alga, while the alga provides the fungus with energy through photosynthesis. This mutualistic relationship allows both organisms to thrive in harsh environments where they wouldn't survive alone.
Is a lichen a plant?
No, lichen is a composite organism of symbiotic fungi with alga or cyanobacteria (single cell plants).
Cyanobacteria or alga living in tissues of fungus is an example of what?
Lichen symbiosis. Lichen is a mutualistic relationship between a fungus and either a cyanobacterium or an alga, where both organisms benefit from each other's presence. The fungus provides structure and protection, while the cyanobacteria or alga provide nutrients through photosynthesis.
Lichens are an alga and a fungus living together in a way that helps both of them This is an example of what?

Symbiosis
Lichen is a symbiotic associated between what two things?
A lichen species is a mixture of one species of fungus and one species of alga so that both species together work as a single organism. Usually the fungus gives the lichen its shape and the alga cells lie spread between the thread-like fungus cells. The alga produce carbohydrates and other organic molecules for both itself and the fungus by means of photosyntesis. The fungus furnishes minerals, humidity and protection for the alga, and exposes the alga for the sun. Both species have usually capability also to grow alone. A lichen multiply usually by buddings that brake off and establishes itself as a new individual.
What is a lichen made up of?
A lichen is a composite organism consisting of a fungus and a photosynthetic partner, usually algae or cyanobacteria. The fungus provides structure and protection, while the photosynthetic partner provides nutrients through photosynthesis.
Is a lichen made up of a fungus and a fungus like protist that live together?
No, a lichen is actually made up of a fungus and an alga or cyanobacterium that live together in a mutualistic symbiotic relationship. The fungus provides a protected environment and absorbs nutrients, while the alga or cyanobacterium photosynthesizes to produce food for both partners.
Is a lichen a parasite?
Mutualism is a symbioses where both partners (symbionts) gain fitness (+/+). Fitness is the success of reproduction of an organism with 1 = breeding and 0 = not breeding. The symbionts that constitute Lichens are a fungus (mycobiont) and alga (photobiont). The association has allowed the lichen fungi and lichen alga to thrive in areas neither could survive in alone and successfully avoid competition. Specifically the fungus gains energy from the photobiont and the alga gains protection from radiation and desiccation which prevents drying out and may be able to obtain salts from the mycobiont. As both smbionts have gained the relationship is considered to be mutualistic. However, it could be argued that the relationship is controlled parasitic as the photobiont is 'incarcerated' by the mycobiont and not a partner.
How is the association between algae and fungi beneficial to each other?
In lichens, the alga prepares food by photosynthesis and feeds the fungus, while the fungus absorbs water from the plant on which it is growing and protects the alga from the environment, hence both take benefit out of each other
