TRANSCRIPT
Fungi
• Saprotrophic– Decomposers– Extra cellular digestion
• Mycelium: fungal body– Composed of many hyphae (individual chains of
cells)
Black Bread Mold (Zygomycota)• Asexual and sexual reproduction
Look at zygospores (diploid reproductive structures) with prepared slides under microscope
Sac fungi (Ascomycota)• Many cause disease– Example: yeast infection
• Observe yeast demo– Single celled– Asexual reproduction through budding
• Aspergillus slide• Penicillium slide• Look for conidiospores: asexual spores– Form on stalks called conidiophores– Individual spores are conidia
Ascomycota life cycle
Club fungi (Basidomycota)• Cap: basidocarp– Forms basidospores at the end
of basidia (stalks)• Typically reproduces sexually
Look at examples and slides but do not dissect
Basidomycota reproduction
Lichens
• Symbiotic relationship between fungi and protista (algae)• Three different shapes:– Foliose: leaf-like – Fruticose: shrubby appearance– Crustose: flattened
• View thallus slide– Find both fungaland algae cells
