Presentation Transcript

  1. Kingdom Fungi

  2. Fungi Structure & Basics • Hyphae: thin strands of cells that make up the fungus body • Hyphae spread into a larger mass (mycelium) • Fruiting body: Above-ground reproductive structure • Cell wall of chiton (common to animals) • Heterotrophs: hyphae release enzymes to absorb nutrients • Classification determined by sexual reproduction methods

  3. Asexual Sporangia produce spores Spores can grow into new hyphae when released Sexual Hyphae from 2 organisms fuse and form a diploid zygospore Zygospore grows new hyphae when released Zygote Fungi

  4. Club Fungi • Basidia: club-like structure that produces sexual spores (located in gills underneath) • Hyphae of two individuals grow into mycelium • Fruiting body created • 2 nuclei fuse to create a zygote • Zygote undergoes meiosis to make spores

  5. Club Fungi

  6. Sac Fungi • Ascus: sac that contain spores during sexual reproduction • Two hyphae grow together to create fruiting body • Spores released • Ex: Yeast, morals, truffles

  7. 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
