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
