  1. POND LIFE STENTOR PARAMECIUM • An Introduction to the • Amoeba • Paramecium • Stentor • Spirostomum • Blepharisma • Euglena AMOEBA SPIROSTOMUM

  2. Protists that move by Pseudopods (the amoeba)

  3. CYTOPLASM PSEUDOPODS NUCLEUS FOOD VACUOLE CELL MEMBRANE CONTRACTILE VACUOLE

  4. Amoeba Movement cytoplasm shifts, pseudopods form Amoeba movement

  5. Amoeba Eating • Pseudopods surround food particle • Food particle becomes encased in a vacuole • Food is then digested and the nutrients are used

  6. Pseudopods start to surround a food particle Pseudopods completely engulf a food molecule to bring it into the cell

  7. Protists that move by Cilia Paramecium Blepharisma Stentor Spirostomum

  8. CYTOPLASM SMALL NUCLEUS CONTRACTILE VACUOLES ANAL PORE PELLICLE LARGE NUCLEUS ORAL GROOVE CILIA FOOD VACUOLE

  9. PARAMECIUM

  10. BLEPHARISMA

  11. STENTORS

  12. SPIROSTOMUM

  13. Protists that move by Flagella (the Euglena)

  14. EYESPOT CONTRACTILE VACUOLE CHLOROPLASTS FLAGELLA NUCLEUS PELLICLE

  15. NUCLEUS • Controls all of the cell’s functions

  16. CELL MEMBRANE • Outer layer of the cell • Lets substances in and out • For the amoeba – very thin and flexible, can change shape

  17. Contractile Vacuole • Collects excess water from the cytoplasm and expels it from the cell

  18. Pseudopods • Used by the amoeba to feed and move • Formed when the cytoplasm shifts within the cell

  19. Cytoplasm • A gel-like material which holds the cell’s organelles (mini organs)

  20. Small Nucleus • Controls reproduction in the paramecium

  21. Pellicle • A stiff but flexible covering • Gives the organism its shape • The cell membrane makes up the inner part

  22. Anal Pore • The place where wastes exit from the paramecium
