  1. KINGDOM PROTISTA The Protists!

  2. General Characteristics • Usually _____________ • Generally live as individuals, some form_______________ • _________________ (contain a nucleus) • Most live in ___________ environments • Some _______________ (plant-like), some _____________(animal/fungus-like) • Most likely evolved _________ bacteria

  3. Animal-like Protists • PROTOZOANS- “________________” • Lack a cell __________ • ___________________ • ___________________

  4. Protozoan Groups • 1) ________________: -use “______________” for movement and food gathering *______________- “_______________”- extension of cytoplasm and cell membrane -some have protective “shells” Ex. ___________

  5. Protozoan Groups • 2) _____________: • Use “_________” for movement and food gathering • __________- hairlike projections • Two kinds of ___________: • Large- life functions • Small- conjugation (reproduction) • Ex. _____________

  6. Protozoan Groups • 3) ______________: • Use “___________” (1-8) for movement • Responsible for some diseases and digestion of some materials • Ex. Trichonympha

  7. Protozoan Groups • 4) ____________________: • Can’t move on own, form “___________” to move from host to host • __________ (feeds on cells and fluids of host) • Ex. __________ (causes malaria)

  8. Plant-like Protists • aka _______________ • __________________ (photosynthetic)- contain chloroplasts • Produce ___________ • Some have flagella

  9. Uni-cellular Algae • 1) ____________________ • Pouch with two ____________ • No cell wall (pellicle- tough, flexible membrane) • Reproduce asexually • Reddish ___________ • Ex. _______________

  10. Uni-cellular Algae • 2) _____________________ • Some _________________ • Usually two flagella • Covered in _________ plates • Many ______________

  11. Uni-cellular Algae 3) ___________________ • ____________-colored chloroplasts • Not all cell walls contain cellulose • Store food as _________ • Reproduce sexually and asexually

  12. Uni-cellular Algae 4) _____________ • Many shapes due to _________ in cell walls • Used in car polish and toothpaste

  13. Multi-cellular Algae 1) Phylum ________________ (____ Algae) • Can live at great depths due to special pigments • Lack flagella • Ex. Irish Moss (algae)

  14. Multi-cellular Algae 2) Phylum _______________ (_____ Algae) • Contains special brown pigment (dark yellow to brown in color) • Some have “bladders” for floating • Ex. Giant Kelp

  15. Multi-cellular Algae 3) Phylum ______________ (______ Algae) • ___________ in cell walls • ___________ is main pigment • Usually live as single cells, can form _______

  16. Fungus-like Protists • Characteristics • ________________ • Most have cell walls • Complex life cycle • Some amoeba-like • Some use flagella • Some produce spores

  17. Fungus-like Protist Groups 1) _________________________: • Moist, flat blobs • Reproduce by producing a ____________ with ____________ • Each spore can develop into a new organism

  18. Life Cycle of Slime Molds Spore Sm. Ameba-like cell Lg. cell w/ many nuclei Spores produced OR Spore Sm. Ameba-like cell Mass of cells Spores produced

  19. Fungus-like Protist Groups 2) __________________ • White, fuzzy (grows on dead fish, etc.) • Sexual and asexual phases of life cycle

  20. Uses for Protists • Using given texts, list several uses for protists:
