Unit 3 - Kingdom Fungi Flashcards
(14 cards)
Are most fungi unicellular or multicellular?
Most are multicellular
Are fungi eukaryotic or prokaryotic?
Eukaryotic
Are fungi heterotrophs or autotrophs?
Heterotrophs
How do fungi feed?
They release digestive enzymes into their surroundings and absorb digested nutrients into their cells
What makes up fungi’s cell walls ?
Chitin
What essential services do fungi provide ecosystems?
Decomposition, recycling of nutrients and soil maintenance
How du fungi reproduce?
Sexually and asexually but they always produce spores (not seeds) which are released and germinate when they find a suitable environment
What kind of relationship do 80% of plants have with fungi?
Symbiotic, fungi provide nutrients
Describe parasitic fungi nutrition.
Fungus usually lives within host organism, then they absorb nutrients from the living cells of a host organism.
Describe predatory fungal nutrition.
Soil fungi with mycelia that have specialized structures can trap prey
Describe mutualistic fungal nutrition.
Fungi form partnerships with other organisms (often plants or protists). Mycelia cover roots of a plant- which increases absorptive surface of plant roots, so they take up more nutrients. Fungus receives sugar from the plant.
Describe saprobial fungal nutrition.
Saprobial fungi are decomposers whose mycelia absorb nutrients from dead or decaying organic matter.
What are lichens?
Composite organisms, they form a unique organism based on a relationship between a fungus and a photosynthetic organism (symbiotic)
List the 5 major phyla of fungi.
Phylum deuteromycota (fungi imperfecti), phylum chytridiomycota (chytrids), phylum zygomycota (zygospore fungi), phylum ascomycota (sac fungi), phylum basidiomycota (club fungi)
