Saprobic =
Parasitic - __________________________________
Mutualistic - ________________________________ ex mycorrhizae
o Lichens are another important example if this we have discussed
Extracellular Digestion -
Question: If your feeding is by absorption – then what type of body do you need to have?
Body Plant – most fungi are multicellular (exception = yeast)
Structure of Fungus – composed of highly branched thread like filaments called _____________
A mass of these hyphae = _______________ has a good surface area for more absorption
Cell wall made of ______________ ( same as exoskeleton of arthropods)
Common to have multinucleated cells – interesting in reproduction
WHY DO FUNGI GROW UP? Ever?
Reproduction:


Asexual
o Using Spores – a spore is _______________________________________________
Sexual
o Using Fruiting Bodies = heterogamous stage of diploid part of their cycle!
 Different in each phyla Basidia, ascus, zygospore
o Alternation of Generations with a haploid stage being dominant!!!
