Presentation Transcript

  1. Protists and Fungi

  2. Kingdom Protista • Plant-like, animal-like, or fungus-like • Heterotrophs or autotrophs • Most unicellular, some multicellular

  3. Plant-like protists: • Algae • Photosynthetic • Basis of the marine food chain • Make most of the oxygen in the atmosphere

  4. Plant-like protists:

  5. Plant-like protists: • Alternation of generations- organism alternates between sexual (using eggs and sperm) and asexual (using spores) reproduction Sea lettuce

  6. Plant-like protists: • Move using flagella • Have chlorophyll for photosynthesis euglena

  7. Animal-like protists: • Protozoans • Move about using cilia, flagella, or false feet • Many are decomposers

  8. Animal-like protists: • Sporozoans reproduce using spores Plasmodium – carried by mosquitoes – causes malaria

  9. Fungus-like protists: • Slime molds: • Water molds and downy mildew:

  10. Kingdom Fungi

  11. What are the characteristics of fungi? Some unicellular, most multicellular Eukaryotes Cell walls made of chitin Body structure is made up of hyphae

  12. Fungi are heterotrophsthey can be: Parasites - Absorb nutrients from the living cells of a host Saprophytes - Decompose waste or dead organic material Mutualists - Live in symbiosis with another organism

  13. Parasitic fungi: Athlete’s foot Bracket fungi

  14. Saprophytic fungi: Mycena Shitake mushroom

  15. Mutualistic fungi: British soldier lichen vesicular-arbuscular mycorrhiza Green shield lichen

  16. Fungi Reproductioncan be asexual: fragmentation budding spores

  17. Fungi Reproductioncan be sexual: Specialized hyphae from two individual fungi meet and form a new individual.
