What is the hypha?
|
The hypha is a filament surrounded by a cell wall made of the polymer chitin.
|
|
|
What are the roles of chitin?
|
Chitin prevents the cell membrane rupture due to osmotic pressure. It allows the hypha to generate internal pressure so it can--
move grow penetrate host tissues or dead organic matter |
|
|
What is mycelium?
|
Mycelium is a mass of hyphae.
|
|
|
How do fungi feed?
|
Fungi feed by absorption. Hyphae secrete digestive enzymes into their surroundings and absorb the digested molecules.
|
|
|
What lifestyles do feeding by absorption support?
|
saprophytic, pathogenic, predatory, and symbiotic
|
|
|
What is the basic structural unit of the fungi body plan?
|
hypha
|
|
|
|
|
|
|
How do fungi reproduce?
|
Many fungi reproduce asexually (via Conidia) or sexually.
|
|
|
How do single-cell fungi (yeast) reproduce?
|
Singe-cell fungi (yeast) reproduce by cell division.
|
|
|
How can mycelium fragments and spores be dispersed?
|
Mycelium fragments and spores can be dispersed by--
wind rain splash animals propulsions (spores) |
|
|
What is the ascocarp?
|
The ascocarp (sac fungi) is a fruiting body (sexual structure) that produces ascospores and facilitates their dispersal.
|
|
|
What is a basidiocarp?
|
A basidiocarp (club fungi) is a fruiting body (sexual structure) that produces basidiospores and facilitates their dispersal.
|
|
|
What forms can fungi and symbiotic fungi be found?
|
Fungi and symbiotic fungi can be decomposers, nitrogen fixers, pathogens, primary producers, or predators in ecosystems.
|
|
|
Which mutualistic relationship is found in most types of plants?
|
symbiotic partnerships
|
|
|
How do lichens contribute to their ecosystems?
|
Lichens (fungi and algae) are primary producers and some fix nitrogen.
|
|
|
Which pharmaceuticals are fungi sources of?
|
penicillin, streptomycin, and cephalosporin
|
|
|
What food and beverages may fungi be found?
|
beer, wine, and spirits (indirectly)
bread cheeses cured meats soy sauce |
|
|
What is the term for a human disease caused by a pathogenic fungus?
|
mycosis
|
|
|
What are some human diseases caused by fungi?
|
ringworm, yeast infection, jock itch, athlete's foot, valley fever
|
|
|
Why are fungal diseases difficult to treat?
|
In fungal diseases, spores are inhaled. More spores are then produced. These spores can enter the bloodstream and colonize other organs.
|
|
|
How do fungi reproduce asexually?
|
Conidia
|
|
|
What does the above-ground structure of fungi represent?
|
The above-ground structure of fungi is the sexual structure.
