KEY CONCEPT Fungi are heterotrophs that absorb their food. 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.

  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 • mycellium • 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
