Lab 5 Flashcards
(24 cards)
All fungi have a wall made of?
chitin (absorbs compounds for metabolism)
Fungi are?
heterotrophs
Hyphae form?`
Mycellium`
3 stages of sexual reproduction in fungi?
Meiosis
Plasmogamy
Karyogamy
Meiosis?
Produces spore that germinate into hyphae
Plasmogamy?
Cytoplasm from two haploid hyphae of opposite mating types fuse to bring nuclei from each parent into one cell.
Dikaryon?
Happens in plasmogamy. nuclei pairing
Karyogamy?
Where the two nuclei fuse together, uniting into diploid zygote
Asexual reproduction?
Spores are produced, germinate hypahe and form mycellium. Mycellium has spore producing structures and cycles
Basidomycetes?
The “mushroom”. Large fibrous network of hyphae
Basidiocarp?
Produces spores
Ascomycetes?
Disperse and propagate asexually produce conidia (asexual spores that create conidiophores)
ascocarp?
produce spores
Yeast?
Ascomycete that is unicellular and doesnt form hyphae. Reproduces by budding.
Majority of fungi are?
Saprophytic
Saprophytic?
derive energy from breakdown of organic material
Decomposers
Break down and absorb from dead organic matter
parasites/pathogens?
Absorb nutrients from cells of living hosts
Mutualist/symbiotic?
Form relations with living hosts
Lichens?
algae and cyanobacteria relations with fungi
mycorrhiza?
Plant relations with fungi
Roles of mycorrhiza?
Mutualistic, increase functional area of root system
types of mycorrhiza?
arbuscular (penetrate root cells) and ectomycorrhizal (srround root)
Lichen types?`
Crustose- thin flat crust
foliose- flat with leaf like lobes
fructicose- shrubby
