Lichens are composed of a fungus in symbiotic union with an alga and having a greenish, gray, yellow, brown, or blackish thallus that grows in leaf like, crust like, or branching forms on rocks, trees, etc.
Lichen usually consists of fungus and algae
Lichen = fungus + algae
Lichens consist of fungi and green algae.
A lichen can also consist of a fungus and a bacterium that can use photosynthesis, a cyanobacterium.
Lichens are composite organisms consisting of a fungus and a photosynthetic partner algae growing together in a symbiotic relationship.
Lichen is a symbiosis of fungus and algae where both the organisms benefit from each other.
fungi and cyanobacteria or algae.
Moss and lichen prepare area for other organisms.
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.
An algae and a fungus can form a symbiotic relationship into what is known as lichen. However, not all lichen contain a type of algae, a type of cyanobacteria and a fungus makes a lichen as well. Algae and Fungus (a.k.a.Lichen) associations may be considered as examples of mutualism, commensalism or even parasitism, depending on the species.
A lichen is 2 or more organisms that have formed a symbiotic relationship, so they depend on each other for survival. Lichens are usually made up of a fungi, could be any kind of fungi and an algae or cyanobacterium.

A lichen is not generally considered to be a parasite.A lichen is composed of two organisms in a symbiotic association. They are a fungus and a photosynthetic partner, usually either a green alga or a cyanobacterium.
when moss or lichen form on rocks these organisms break down rocks to the point it becomes soil
The two parts of the lichen help each other by making it so that the algal part of a lichen provides food while the phycobiont provides protection.
Lichen is a symbiotic relationship between a fungus and algae. The algae are the autotrophic component of this partnership. Green algae and cyanobacterium are types of algae commonly found in lichen.
Moss and lichen prepare area for other organisms.
They are composite organisms of fungus and algae
LichensA lichen (LIE kuhn) is a combination of a fungus and an alga that grow together. The alga actually lives inside the protective walls of the fungus. The resulting organism is different from either organism growing alone. The lichen is a result of a mutualistic relationship. But the merging of the two organisms to form a lichen is so complete that scientists give lichens their own scientific names.Shortened answer: Lichen
That is true
Lichen is considered to be a scavenger. They are commonly organisms that contain fungus and usually have a photosynthetic associate that they grow with.
Lichen
Lichen is an example of Mutualism because it consists of a fungus and an alga growing together. the fungus provides support in which the alga can grow. The alga makes food by photosynthesis using the water that the fungus has stored. The fungus also takes in minerals to be converted into materials for growth. together the two organisms form a structure that can live on the surfaces of rocks in harsh conditions where other organisms cannot survive.
