  1. Biology 101Unit 3B Day Seven

  2. Before Class starts… • Make sure you turn in your work from yesterday • Algae Notes- let me stamp them • Algae lab- turn in

  3. Getting Started Wednesday 5-22 • Why are algae of importance to all living things? • Give at least three reasons.

  4. Today’s assignments: • Fungi Notes- go to MHS website and copy down notes from my blog (under files) • Survey lab

  5. Fungi • Characteristics • Eukaryotic • Most are multicellular – except yeasts • Nonmotile • Heterotrophic – acquire nutrients by absorption • Release digestive enzymes that digest plant cell walls and then grow into them • Mode of nutrition specializes fungi as: Saprophytes, parasites or mutualistic

  6. Fungi • Classified according to their spore producing structure • Typical Fungi • Hyphae – individual filaments • Mycelium – masses or network of hyphae • Hyphae have cell walls made of chitin • Rhizoid – root like hyphae • Stolons – Hyphae that run along the surface of the food

  7. Types of Fungi • PHYLUM ZYGOMYCOTA • Zygomycetes • Terrestrial molds • Reproduce using sporangiophores that are capped by a sporangia containing spores. • Ex: Rhizopus stolonifer common bread mold

  8. Types of Fungi • PHYLUM BASIDIOMYCOTA • Club fungi • Reproduce using club-shaped structure called basidia that form basidiospores. • Ex: mushrooms, shelf fungi

  9. Types of Fungi • PHYLUM ASCOMYCOTA • Sac fungi • Reproduce by producing spores in an ascus- “little sac” • Ex: truffles, morels, yeast, dutch elm disease

  10. Types of Fungi • PHYLUM DEUTEROMYCOTA • Imperfect fungi • Do not know how they reproduce • Ex: penicillin, ringworm

  11. Fungi • Reproduction (handout 17.17) • Asexually – spores, fragmentation and budding • Sexually

  12. Quiz 7 • How are fungi classified? a. color b. movement c. reproduction • Fungi that break down dead material are classified as ? a. saprobes b. parasites c. mutualistic • Some fungi produce lightweight reproductive cells called ? a. gametes b. mycelium c. spores • The rootlike structures found in fungi are called? a. mycelium b. stipe c. rhizoid • The top of a mushroom is called? a. cap b. gills c. stipe
