Fungi
Spore producing heterotrophs that include chitin in their cell wall
Spore
Little asexual reproductive bodies
Heterotrophs
Require carbon from outside source
Chitin
Nitrogen containing polysaccharide
Mycelium
Body of a fungus
Hypha
each filament in the mycelium
Relationship to other Eukaryotes
more closely related to animals than they are with plants heterotrophic Chitin, (exo-skelleton)
5 mayor groups of Fungi
I. ChytridsII. Zygote FungiIII. Glameromycetes IV. Sac Fingi V. Club Fungi
Chytrids
primitive, early ancestor, require moist or wet environments they produce spores that swim (with flagellum) decomposers= saprophytes, recycle remains thus recycling materials they infect/ harm amphibians because of human movement
Zygote Fungi
produce zygospore during reproduction 2 hyphi join and exchange genetic material into a zygospore= only diploid stage-most of their life cycle is spent as a haploid mycelium [They are common in moldy bread, fruit or veggies because they are sapping nutrients
Glameromycetes
Most important in plant root cells 90% of plants have an association with roots and fungi in soil. Micronutrients and and phosphates from soil exchange of rare micronutrients, and photosynthesis by the plants. -They are known to produce asexual -mutualism between fungi and roots -fungi offers micronutrients -plant offers sugars (carbohydrates)-soil fungus= mycorrhizae
Club Fungi
Important decomposers of woodhave the largest most complex fruiting bodies of all fungi Cap/ StalkCap= underneath the cap are where the spores are reproduced
Lichens
are not just fungi made out of sac fungus + green algae or sac fungus + siano bacteria
Mutually beneficial partnership with plants
Fungi can live in stems, leaves or roots
mutualism
alage - ascomycetes ascomyceted - siano bacteria
3 main groups
i. Fruticose ii. Folioseiii. Crustose each indicates growth form of lichens
