Mostly multicellular Heterotrophic mostly terrestrial Mostly decomposers cell wall made from chitin reproduce sexually using spores and asexually lack true roots, stems and leaves some are edible while others are poisonous

New cards
Hyphae
elongated cells that form a branching filamentous structure
3
New cards
Septate hypha
hypha separated by cell walls
4
New cards
Nonseptate hypha
hyphae not divided into individual cells
5
New cards
Mycelium
multiple hyphae forming a branching network of filaments
6
New cards
Ascomycota
sexual spores formed in sac-like "ascus" important for fermentation and food very diverse
7
New cards
Basidiomycota
produces mushroom-cap mostly decomposers includes puffballs, and bracket fungi
8
New cards
Zygomycota
mostly soil fungi includes bread and fruit moulds multinucleate hyphae non-septate
9
New cards
Chytridiomycota
mostly decomposers some unicellular some multicellular some have swimming spores
10
New cards
Glomeromycota
all form symbiotic relationships with plant roots
11
New cards
Extracellular Digestion
Excretion of digestive enzymes digestive enzymes degrade substances digested good absorbed by hyphae
12
New cards
Lichen
Partnership between fungus and cyanobacteria or green algae
13
New cards
Mycorrhizae
partnership between fungus and plant roots
14
New cards
Reproduction of fungi
using spores
15
New cards
Spores
adaptation to life on land new species will disperse to new locations contains a reproductive cell that forms non-motile dispersed by wind
16
New cards
sexual reproduction
used when environmental conditions are poor some fungi show dimorphism which is the ability of certain fungi to switch between unicellular yeast and multicellular filamentous growth forms in response to changing environmental cues.
17
New cards
Fragmentation
part of the mycelium becomes separated and begins a life on its own
18
New cards
Budding
a small cell forms and gets pinched off as it grows to full size
19
New cards
asexual spores
production of spores by a single mycelium
20
New cards
Spores are made of:
Dehydrated cytoplasm protective coar haploid cell wind, animals, water and insects spread spores
