1. identify what two kinds of organisms make up a lichen?

imperfect fungi
this group includes all of the fungi that do not fit into the other groups. imperfect fungi do not reproduce sexually. this group includes some fungi that are harmful to humans and some that are useful.
most imperfect fungi are parasites that cause diseases in plants and animals. one kind of imperfect fungus causes a skin disease called athletes foot. another kind of imperfect fungus produces aflatoxin. aflatoxin is a poison that can cause cancer. some imperfect fungi are used to make medicines, including the antibiotic penicillin. other imperfect fungi are used to produce cheeses and soy sauce.
what are lichens?
a lichen is the combination of a fungus and an alga. the alga lives inside the cell walls of the fungus. this creates a mutualistic relationship. in a mutualistic relationship, both organisms benefit from living closely with another species. even though lichens are made of two different organisms, scientists give lichens their own scientific names. this is because the two organisms together function like one organism.

Explanation:

1. The visible mushroom (fruiting - body) is not the largest part. The largest part of a fungus is usually the mycelium, which is a network of fine threads (hyphae) hidden in the soil or substrate. The mycelium can spread over a large area.
2. Athlete's foot is a skin - disease caused by an imperfect fungus. Aflatoxin - producing fungi can cause cancer.
3. A lichen is made up of a fungus and an alga. They have a mutualistic relationship.

Answer:

1. No. The largest part of a fungus is usually the mycelium, which is not visible in the picture. The mycelium is a network of hyphae that can spread widely in the soil or substrate.
2. Athlete's foot; diseases caused by aflatoxin - producing fungi
3. A fungus and an alga
