|
Absorptive Heterotrophy |
Fungi live by this. Digestive enzymes secreted outside of body to break down large food. |
|
|
Saprobes, parasites, and mutualists. |
S- absorb from dead P- absorb from living M- both benefits |
|
|
Opisthokonts |
Flagellum |
|
|
Mycelium and hyphae. |
Mycelium is whole body, and hyphae are the filaments. Cell walls made of chitin. |
|
|
Rhizoids |
Mushrooms. Modified hyphae. |
|
|
Pathogens |
Infections. |
|
|
Black Stem |
Involves two hosts (wheat and barberry) |
|
|
Lichens |
Unicellular green alga, cyanobacteria. Can grow on exposed surfaces. |
|
|
Lichen information |
Hyphae absorb mineral nutrients and provide moist environment for photosynthetic cells. Can reproduce by fragmentation of thallus or one or a few photosynthetic cells surrounded by hyphae. |
|
|
Lichens information part 2 |
Grow very slowly. Get minerals and water absorbed from rock. |
|
|
What are lichens used for? |
To gauge air pollution around cities and track pollutants and their effects. |
|
|
Mycorrhizae |
Associations of fungi and plant roots. |
|
|
Ectomycorrhizae |
Fungus wraps around individual cells in root but does not penetrate cells. |
|
|
6 major groups |
Microsporidia, chytrids, zygospore (zygomycota), arbys (glowering it's), sac (ascomycota), club (basidiomycota). |
|
|
Chytrids |
Aquatic. Flagella. Sex and asex. Parasitic or saprobic. Responsible for world wide decline of amphibian populations. |
|
|
What do sac and club fungi have in common? |
They both have a dikaryon life stage. |
|
|
Plasmogamy and karyogamy. |
P- fusion of cytoplasm K- fusion of nuclei Happens in sac and club |
|
|
Figure about dikaryotic. |
Plasmogamy occurs (dikaryotic mycelium), ascoma (fruiting structure), karyogamy (fertilization). |
