  1. KEY CONCEPTFungi are heterotrophs that absorb their food.

  2. Fungi are adapted to absorb their food from the environment. • Plants and fungi have different traits: • Fungal cell walls are made of chitin. • Plant cell walls are made of cellulose. • Plants have chlorophyll and photosynthesize. • Fungi absorb food through hyphae. • Plants and fungi have similar traits: • Both are nonmoving. • Grow underground and aboveground. • May produce spores.

  3. Fungi are multicellular organisms, with the exception of yeasts. • hyphae • mycelium • fruiting body

  4. Fungi come in many shapes and sizes. • Primitive fungi are aquatic and have flagellated spores. • Sac fungi form a sac that contains spores for reproduction (called ascus, plural= asci). • Yeasts are single-celled sac fungi. • Morels and truffles are multicellular sac fungi.

  5. Also includes fungi used to ferment certain foods. • mycorrhizae belong to this group • form zygospores during reproduction • Bread molds are often found on spoiled food.

  6. include mushrooms, puffballs, and shelf fungi • reproductive structures called basidia • Club fungi have fruiting bodies which are club-shaped.

  7. Fungi reproduce sexually and asexually. • Most fungi reproduce both sexually and asexually. • Yeasts reproduce asexually through budding. • Yeasts form asci during sexual reproduction.

  8. Multicellular fungi have complex reproductive cycles. • distinctive reproductive structures

  9. All fungi form spores and zygotes.

  10. life cycles may include either sexual or asexual reproduction or both • Multicellular fungi have complex reproductive cycles.

  11. Club Fungi

  12. Spores will land Fungus #1 mycelium grows underground….Fungus #2 mycelium grows underground . . Two fungi grow together and fuse Diploid fruiting body grows from the mass Haploid spores created & released from the underside of the fruiting body . . . . . ground

  13. Spores will land New hyphae will grow into a new mycelium . Cycle repeats . ground

  14. Lichens • Fungus + blue-green bacteria or green algae • Mycelium of fungi surrounds the green organism • Grow on rocks, soil, trees • Mutualistic relationship • Algae/bacteria: provides food • Fungus: benefits unclear (warmth, substrate to grow in) • Food source & help create soil
