Transcript and Presenter's Notes

Title: Kingdom Protista


1
Kingdom Protista
  • Fidgety little critters!

2
What is a Protist?
  • Eukaryotic
  • Has a nucleus!
  • Mostly single celled
  • Classified by
  • MOVEMENT
  • OBTAIN FOOD
  • Animal-like
  • Heterotrophic
  • Plant-like
  • Autotrophic (have chloroplasts)
  • Fungus-like
  • Parasitic
  • REPRODUCE

3
Animal-like Protists Sarcodinia
  • Movement
  • By pseudopods
  • Little blobs of cytoplasm
  • Means Fake Feet
  • Consumer Nutrition
  • Surround meal and bring into food vacuole
  • Phagocytosis!
  • Reproduction
  • Binary Fission
  • Organism
  • Amoeba amoeba

4
Animal-like Protists Ciliates
  • Movement
  • By cilia
  • Little hairs that beat like oars
  • Consumer Nutrition
  • Food is swept in by cilia to GULLET
  • Contractile vacuoles collect and spit out water
  • Reproduction
  • Binary fission AND conjugation
  • Organism
  • Paramecium caudatum, Stentor coeruleus,
    Blepharisma

5
Plant-like Protists Flagellates (Volvox)
  • Colonial organism
  • Hundreds of individual cells live together
  • Movement
  • Long, whip-like flagella
  • Whole colony moves together!
  • Nutrition
  • Autotrophic
  • Contain chloroplasts! (Hence green color!)
  • Reproduction
  • Binary fission

6
Euglenophytes The plant-like animal protist
  • NO CELL WALL
  • Has pellicle
  • MOVEMENT
  • TWO flagella
  • NUTRITION
  • Autotrophic (chloroplasts)
  • Can be heterotrophic when no sunlight!
  • Red eye spot helps organism to find sunlight
  • REPRODUCTION
  • By binary fission
  • ORGANISM
  • Euglena

EYE SPOT
