  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. • PlantsFungus • Cell wall = cellulose Cell wall = chitin • Photosynthesis = chloroplast Heterotroph = absorb food • through hyphae

  3. Fungi are multicellular organisms, with the exception of yeasts. • hyphae: long branching filaments • mycelium: mass of branching hyphae • fruiting body: specialized spore producing body

  4. Fungi come in many shapes and sizes. • Primitive fungi are aquatic and have flagellated spores. • Sac fungi form a reproductive sac, or ascus. • Yeasts are single-celled sac fungi. • Morels and truffles are multicellular sac fungi.

  5. form zygospores (diploid spore) during reproduction • mycorrhizae (are found on roots of certain plants) belong to this group • Bread molds are often found on spoiled food.

  6. reproductive structures called basidia • include mushrooms, puffballs, and shelf fungi • 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. life cycles may include either sexual or asexual reproduction or both • Multicellular fungi have complex reproductive cycles.

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

  11. All fungi form spores and zygotes.

  12. KEY CONCEPTFungi recycle nutrients in the environment.

  13. Fungi may be decomposers, pathogens, or mutualists. • Fungi and bacteria are the main decomposers in any ecosystem. • decompose dead leaves, twigs, logs, and animals • return nutrients to the soil • can damage fruit trees and wooden structures

  14. human diseases include ringworm and athlete’s foot • plant diseases include Dutch elm disease • Fungi can act as pathogens.

  15. lichens form between fungi and algae • Fungi can act as mutualists. • mycorrhizae form between fungi and plants

  16. Fungi can act as mutualists. • relationships form between fungi and some insects

  17. Fungi are studied for many purposes. • Fungi are useful in several ways. • as food • as antibiotics • as model systems for molecular biology
