POND LIFE

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

9. Amoeba Movement cytoplasm shifts, pseudopods form Amoeba movement

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

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

13. Protists that move by Cilia Paramecium Blepharisma Stentor Spirostomum

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

20. BLEPHARISMA

27. STENTORS

35. SPIROSTOMUM

38. Protists that move by Flagella (the Euglena)

39. EYESPOT CONTRACTILE VACUOLE CHLOROPLASTS FLAGELLA NUCLEUS PELLICLE

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

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

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

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

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

48. Small Nucleus • Controls reproduction in the paramecium

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

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