  1. Unit 10:Classification & Taxonomy: Protista & FungiNotes #3

  2. Protista • Kingdom Protista: • Over 3.5 billion years ago • Most diverse Kingdom • Animal-like – Protozoan • Plant-like – Algae • Fungus-like – Slime molds • Characteristics: • Eukaryotic – but no tissues • Single celled • Most = heterotrophic • Free-living – some parasitic

  3. Protista cont. • Protista Reproduction: • Some asexual = binary fission • Some = multiple fission • Some Conjugation • Protista Adaptations: • Eyespots = detect quality & quantity of light • Cysts = dormant form – protects against pH, temperature, lack of nutrients, etc.

  4. Algae & Fungus • Algae: • Plant-like protista • Unicellular or multicellular – can be colonial • Classified by pigments – some are bioluminescent • Autotrophic • Fungus: • Fungus-like protista • Obtain energy by decomposing organic materials • Divided into 3 phyla: • Plasmodial Slime Molds = reproduce by spores • Cellular Slime Molds = reproduce by cell division • Water Molds & Mildew = reproduce by flagellated reproductive cells

  5. Kingdom Fungi • Fungi: • Eukaryotic • Multicellularheterotrophs • Saprophytic = absorb dead organisms • Ex: fungus, molds & yeast • Reproduction: • Asexual: • Spores • Fragmentation • Budding • Sexual: • Not male or female = + or – • Fuse together & then disperse

  6. Fungi cont. • Fungi Classification: • 3 phyla • Based on reproduction & structure • Over 100,000 species • Special relationships: • Lichens: • Fungus provides moisture, shelter & anchorage between fungus & photosynthetic partner • Humans & fungi: • Skin infections • Can be toxic • Vaccines, antibiotics & antinflammatory medication

  7. Fungus Classification:Fungus may be:
