- absorptive heterotrophs: release digestive enzyme, breaks down, absorbs
- Saprobes: decomposers
- cell wall: made of chitin
- most multicellular, some not, eg. yeast is unicellular
- terrestrial
- spore producing
- found mostly underground: exposed to air lose water/die, reproductive
structures above ground (fruiting structure)
- made of hyphae, bunch of hyphae = mysilium
Fruiting structure: produces spores (unicellular reproductive structures) by meiosis
- spores produced asexually
- dispersed in wind and in water
Filamentous body plan:
- long banched filament = hyphae increase surface area for efficient
- tangled mass of hyphae = myselium
- septate = cross walls, pores for diffusion of enzymes/organelles
- coenobytic = no cross walls, multiple nuclei but no divisons
- adapted for different jobs:
eg. predation: release digestive enzymes
eg. parasitism
eg. mutualism: Mycorrhize = fungi associated with plant roots
- ecto: outside, endo: inside, fungus receives
carbs, plant receives minerals and water
- fossils older than vascular plants of
Lichen: symbiosis between green algae and fungus
-pioneer species, tundra animal food, break
down rock with acid = soil
-diverse morphology, color, species involved
-air pollution indicators, sensitive to toxin
Ants: leaf cutter ants feed fungus with leaves
eg. pathogens: to plants and animals
Phylogeny: flourished in Permian, closely related to animals
Life cycles:
Haplontic life cycle: mature organism produces haploid gamete which come
together to make a zygote with produces haploid spores through meiosis
- only zygote is haploid
