Unit 2 - Biodiversity

Kingdom Protista
  • Eukaryotic (all members of this Kingdom have a nucleus and organelles bound with membranes)
  • Most Protists are unicellular, but there are many that are multicellular
  • Autotrophic, Heterotrophic, and some alternate.
  • Cell walls may or may not be present
major divisons
Major Divisons
  • Algae (Plant like protists)
  • Protozoans (Animal like protists)
  • Slime Molds (Fungus like protists)
  • Protists are thought to be the ancestors of the other 3 Eukaryotic Kingdoms (Plantae, Animalia, Fungi)
algae plant like protists
Algae – Plant Like Protists
  • Autotrophic
  • Do have cell walls
  • Most immobile (meaning they cannont move on their own)
  • Think about the stuff you would find in a dirty pool, or pond scum.
protozoans animal like protists
Protozoans – Animal Like Protists
  • Heterotrophic
  • NO cell walls
  • Most can move
    • Cilia
      • (hair like)
    • Flagella
      • (tail like)
    • Pseudopod
      • (false foot)
  • Immobile ones are parasites.
slime molds fungus like protists
Slime Molds – Fungus-like Protists
  • Heterotrophic decomposers
  • Have cell walls, but not made of chitin
  • Produce spores

Contributions

Negative Aspects

  • Autotrophic protists primary component of phytoplankton
  • Carry our between 70-80% of the Earth’s photosynthesis
  • Phytoplankton and Zooplankton are the base of the world’s food chains.
  • Many cause disease
    • Malaria
    • African Sleeping Sickness
    • Amebic Dysentery
  • Cause Red-Tides
  • Cause algae blooms
