Presentation Transcript

  1. Characteristics of Fungi Kingdom Fungi • Characteristics • Heterotrophic – obtain energy by decomposing organic material • Structures are made of the same type of filamentous cell • Cell walls contain chitin • Go through nuclear mitosis – nucleus divides with no cytokinesis

  2. Characteristics of Fungi Structures • Their bodies are made up of slender woven filaments called hyphae. • Hyphae form mycelium, a tangled mass that make up the fungi structures.

  3. Characteristics of Fungi Nutrients • Fungi are decomposers. • They obtain energy by secreting digestive enzymes and absorbing the decomposed nutrients into their cells. • (Label diagram on notes)

  4. Characteristics of Fungi Reproduction • Most fungi reproduce by releasing spores that are produced asexually or sexually. • Spores are haploid, and fuse together to make the diploid stage of the life cycle • Spores are small and light to stay suspended in air.

  5. Fungal Diversity Zygomycetes • Common Name: Thread Fungi • Structure: Stolons grow along surface; rhizoids anchor to food source • Reproduction: tough zygosporangia produce spores • Examples: bread mold; soil fungi (Label diagram on notes)

  6. Fungal Diversity Ascomycetes • Common Name: Sac Fungi • Structure: Spore sacs called asci • Reproduction: sexual with spores or • asexual by budding (yeast) • Examples: Baker’s yeast, cup fungi, morel mushrooms

  7. Fungal Diversity Basidiomycetes • Common Name: Club Fungi • Structure: Club-shaped basidia line gills • Reproduction: Sexual; spores form on basidia • Examples: Mushrooms, puffballs, shelf fungi

  8. Fungal Diversity Deuteromycota • Common Name: Imperfect Fungi • Structure: Many types • Reproduction: Asexual by spores and budding • Examples: Penicillium, infectious yeast

  9. Fungal Partnerships Symbiotic Relationships • Mycorrhizae • Mycorrhizae are a symbiotic relationship with plants • Fungus transfers minerals to a plant’s roots • Roots supply carbohydrates to the fungus.

  10. Fungal Partnerships Symbiotic Relationships • Lichens • Symbiotic relationship between fungus and photosynthetic algae or protist • Fungus protects the photosynthetic partner and provides minerals. • The photosynthetic partner provides carbohydrates.
