Phylum Chrytidiomycota-> Allomyces Gametophyte

larger bulb= female gametangia

bulb at end=male gametangia

Term
[image]
Definition

Phylum Chritidiomycota-> Allomyces Sporophyte

bulbs at end=sporangia

Term
what are the flagellated cells in their life cycle and what do they suggest
Definition

hyphae

they suggest plasmogamy

Term

Definition

Phylum Zygomycota-> Rhizopus Combination

circle in the middle=zygosporangium

fused cones at the ends=fused hyphae

Term

Definition

Phylum Zygomycota-> Rhuzopus Sporangia

bulb at end=sporangium

Term
rhizopus produce spores sexually and asexually; how is this beneficial to the population
Definition
rapid reporoduction and mutation

Phylum Ascomycota (Sac Fungi)-> Peziza apothecium

circlular dots in the middles=ascospores

Term

Definition

Phylum Ascomycota (Sac Fungi)-> Penicillium

dots at end=conidophores

Term

Definition
Phylum Ascomycota (Sac Fungi)-> Aspergillus conidiophores
Term
what are conidiophores? what do they produce?
Definition
stalk like reproductive structures that produce conida
Term

Definition
Phylum Ascomycota (Sac Fungi)-> Morchella (Morel Mushroom)
Term
what is the saclike reproductive structure that produces spores in Phylum Ascomycota?
Definition
the ascocarp in between the gills
Term

Definition
Phylum Basidiomycota (Club Fungi)-> Coprinus mushroom gill
Term
[image]
Definition
Phylum Basidiomycota (Club Fungi)-> Earth Sacs
Term
[image]
Definition
Phylum Basidiomycota (Club Fungi)-> Button Mushroom
Term
what benefit does fungus contribute to symbiosis> the algae?
Definition

fungi extract carbs from the algal photosynthesis.

fungi provides algae with more water and minereals due to its larger surface area

Definition

Lichen Body Type

Foliose (flared up ends)

Term
grows on trees in a cuplike form
Definition

fruticose

Term

Lichen Thallus
Term

Definition
endotrophic mycorrhizae
Term
[image]
Definition
ectotrophic mycorrhizae
Term
saprobic fungi
Definition

derives its nourishment from nonliving or decaying organic matter

ex: Phallus ravenelli

Agaricus xanthodermus

Term
parasitic fungi
Definition

gets nourishment from live tissues of various organisms

ex:oomycetes

Term
mutualistic fungi
Definition

where both the fungi and its host benefit from the fungal infestation

ex: lichen

Term
chrytidiomycota
Definition

oldest known living fungi

have flagellated stage 

 

Term
zygomycota
Definition

referred to as conjugating fungi which refers to life history stage when 2 mycelia fuse

cytoplasm not divided into separate cells

includes decomposers and symbionts

 

Term
ascomycota
Definition

sac fungi

largest group of fungi

name derives from ascus: the spore containing capsules produced during sexual reproduction

develop conidiophores

 

Term
basidiomycota
Definition

club fungi

includes mushrooms, toadstools, puffballs, bracket fungi, chanterelles, and earth stars

fruiting body produces basidiocarp and consists of stripe and cap

underside of cap divided by radiating gills which bear basidia

Term
mycorrhizae
Definition
symbiotic relationship between a fungus and a plant root
Term
lichens
Definition

symbiotic combinations of a fungus (usually ascomycote) and a green algae (usually trebouxia) or cyanobacterium (usually nostoc)

lichen body=thallus

actually controlled parasitism: fungus limits and controls algae's growth often penetrating algal cells w/haustoria
