  • Protists

  • What is a Protist?

    ! Junk drawer Kingdom ! Eukaryotes ! Mostly Unicellular &

    Multicellular

    ! Autotrophic & Heterotrophic

  • What is a Protist?

  • Three Categories

    ! Animal-like ! Fungus-like ! Plant-like

  • Animal-like Protists ! Heterotrophs

    ! Called Protozoans

    ! Four types based on how they move or live

    ! Protozoans with Pseudopods ! Protozoans with Cilia ! Protozoans with Flagella ! Other Protozoans

  • Protozoans with Pseudopods

    ! Called Sarcodines

    ! Move with pseudopods (false foot)

    ! Have a contractile vacuole to expel extra water

    ! Example: Ameba

  • Protozoans with Pseudopods

  • Protozoans with Cilia

    ! Called Ciliates

    ! Move with cilia (hair like structures)

    ! Complex cells - two nuclei

    ! Asexual & sexual reproduction

    ! Example: Paramecium

  • Protozoans with Cilia

  • Protozoans with Flagella

    ! Called Zooflagellates

    ! Use Flagella to move (whip like structure)

    ! Symbiosis - interaction between two species where at least one species benefits

    ! Mutualism - both species benefit.

    ! Example: Giardia

  • Protozoans with Flagella

  • Other Protozoans

    ! Called Sporozoans

    ! Parasites An organism that lives on or in a host and causes harm to the host

    ! Example: Plasmodium

  • Fungus-like Protists

    ! Heterotrophs (animal like)

    ! Cell wall (Plant like)

    ! Spores to reproduce

    ! Examples: Water Molds, Downy Mildews, Slime Molds

  • Plant-like Protists

    ! Commonly called algae

    ! Autotrophs

    ! Live: soil, bark of trees, fresh water, salt water

    ! Examples: Euglenoids, Dinoflagellates, Diatoms, Green Algae, Red Algae, Brown Algae

  • Plant-like Protists

  • Protists and Us

    Helpful

    ! Food source to organisms

    ! Makes most of earths oxygen

    ! Toothpastes

    ! Household scouring products

    ! Swimming pool filters

    ! Insecticides

    ! Ice cream

    ! Hair conditioner

    ! Nutrient-rich delicacy

    ! Thickener for pudding and salad dressing

  • Protists and Us

    Harmful

    ! Parasitic to humans

    ! Cause malaria

    ! Attack food crops
