Hyphae |
-In multicellular fungus to enhance growth and nutrition absorbance -with porous cross walls (septae) -without porous cross walls (coenocytic) |
|
Mycelium |
network of branched septae -increase in surface to volume ratio |
|
Ectomycorrhizal Fungi |
hyphae cover root surface and grow into extracellular spaces of root cortex |
|
Arbuscular Mycorrhizal Funi |
Branching hyphae extend through root cell wall |
|
Plasmogamy Phase |
fusion of cytoplasm, transfer of haploid nucleus to cell of opposite mating type -recognize different mating types by pheromones |
|
Karyogamy Phase |
fusion of the haploid nucleus's form a diploid zygote nucleus -haploid nuclei may reproduce by mitosis before fusing -ONLY time when fungal cells are diploid |
|
Meiosis Phase |
production of genetically unique haploid sexual spores |
|
Chytrids |
-found in fresh water and terrestrial habitats -decomposers, parasites, mutualists -unique by their flagellated spores (zoospores) -Paraphyletic- common ancestor but not all descendants |
