What categories of fungi cause human diseases?
Fungi cause three different types of human illness: poisonings, parasitic infections, and allergies. Many poisonous mushrooms are eaten by mistake because they look like edible mushrooms. Parasitic yeasts cause candidiasis, ringworm, and athlete's foot.
What are two ways fungi can cause disease in humans?
Fungi can cause disease through:
- Replication of the fungus (fungal cells can invade tissues and disrupt their function)
- Immune response (by immune cells or antibodies)

Types of Fungal Skin Infections and Treatment Options. Although there are millions of species of fungi, only about 300 of them can actually cause infections in humans.
Which are the three ways in which fungi cause illness in humans quizlet?
- Hypersensitivity – person has allergic reaction to fungal components.
- Intoxication – fungus produces a toxin that is ingested.
- Immune suppression – fungus destroys all red blood cells.
- Infection – fungus grows on body as a mycosis.
What is lichen and mycorrhiza?
The fungus part of lichen benefits from the algae or cyanobacteria as they produce food by photosynthesis. Mycorrhizae – This association is between fungi and plant roots, where the fungi derive photosynthetic sugars from the plants, and they assist the plant by facilitating the uptake of mineral nutrients and water.
What is the most common pathogenic fungus for humans?

What are the two forms of fungi?
Fungi can be divided into two basic morphological forms, yeasts and hyphae.
What are the categories of fungi?
Fungi are usually classified in four divisions: the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi). Placement into a division is based on the way in which the fungus reproduces sexually.

How do fungi make people sick quizlet?
How do fungi cause disease? The tissue damage associated with fungal infections results primarily from direct invasion of tissue, with subsequent displacement and destruction of vital structures, coupled with toxic effects of the inflammatory response.
What trophic level in a food chain would lichen occupy How do you know?
Lichen: A symbiotic relationship between an alga (autotrophic phycobiont or photobiont) and a fungus (heterotrophic mycobiont). This type of symbiotic relationship is mutually beneficial to both organisms. Primary Consumers: Plant eaters (herbivores) that occupy the second trophic level of a food chain.
How is lichen mutualism?
Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyanobacteria, that are photosynthetic. The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.
What are the 2 type of fungi and their characteristics?
Saprophytic – The fungi obtain their nutrition by feeding on dead organic substances. Examples: Rhizopus, Penicillium and Aspergillus. Parasitic – The fungi obtain their nutrition by living on other living organisms (plants or animals) and absorb nutrients from their host.
What are two main categories of fungi?
Two major functional categories of fungi are saprophytic fungi and mycorrhizal fungi. Saprophytic fungi decompose nonliving organic matter and they are important agents in soil mineralization processes and carbon cycling.

Viruses cause many human diseases. In addition to the flu and HIV, viruses cause rabies, measles, diarrheal diseases, hepatitis, polio, cold sores and other diseases (see Figure below). Viral diseases range from mild to fatal. One way viruses cause disease is by causing host cells to burst open and die.
