  1. Kingdom protista

  2. What are the 5 kingdoms? • Monera • Protista • Fungi • Plantae • Animalia

  3. Quick Moneran review… • Pro or Eu? • 3 types, based on shape?

  4. Viruses? • Living or nonliving? • How do viruses reproduce? • Lytic or lysogenic—dormant/”pause”/activated by stress? • Lytic: attachment entry (injection of DNA) replication/synthesis assembly lysis and release

  5. KINGDOM PROTISTA CHARACTERISTICS • MOSTLY UNICELLULAR, SOME MULTICELLULAR • CAN BE HETEROTROPHIC OR AUTOTROPHIC • MOST LIVE IN WATER • ALL ARE EUKARYOTIC

  6. FACTS • ABOUT 200, 000 SPECIES IN KINGDOM PROTISTA, RANGING FROM SMALL UNICELLULAR AMOEBA TO 100m SEAWEED • MOST DIVERSE KINGDOM • DEFINITION: PROTIST-ANY ORGANISM THAT IS NOT A PLANT, ANIMAL OR FUNGUS • CLASSIFIED BASED ON HOW THEY OBTAIN FOOD AND ON HOW THEY MOVE

  7. HOW DO THEY MOVE? • FLAGELLA-SINGLE HAIR-LIKE PROJECTION; WHIP-LIKE MOTION • CILIA: SHORT HAIR-LIKE PROJECTIONS,BEAT LIKE MOTION • PSEUDOPODIUM=PSEUDOPODS=FALSE FEET-CELL MEMBRANE EXTENDS OUTWARD IN ANY DIRECTION AND PULLS ORGANISM FORWARD

  8. PARASITIC? • SOME PROTISTA ARE PATHOGENIC (DISEASE CAUSING) AND/OR PARASITIC • DISEASES: MALARIA, AFRICAN SLEEPING SICKNESS, GIARDIA

  9. PROTISTA CAN BE… • ANIMAL LIKE--- CALLED *PROTOZOA • PLANT LIKE---CALLED *ALGAE • FUNGUS LIKE

  10. LET’S DO PROTOZOA FIRST • PROTOZOA CAN HAVE • PSEUDOPODS • FLAGELLA • CILIA • OR BE PARASITIC

  11. PROTOZOA: PSEUDOPODS • EX. AMOEBA

  12. PROTOZOA: FLAGELLA • EX. EUGLENA

  13. PROTOZOA: CILIA • EX. PARAMECIUM

  14. PROTOZOA: PARASITIC • EX. SPOROZOANS • CAN CAUSE MALARIA

  15. REMEMBER: • PROTISTA CAN BE *ANIMAL-LIKE -PROTOZOA—WE JUST DID THIS!  *PLANT-LIKE—ALGAE (ABOUT TO DO THIS ONE!) *FUNGUS-LIKE

  16. PROTIST: ALGAE MULTI AND UNICELLULAR LOOK LIKE PLANTS-NO ROOTS, STEMS, LEAVES CONTAIN CHLOROPHYLL EX. VOLVOX

  17. MORE ALGAE • SPRIROGYRA

  18. MORE ALGAE • DIATOMS • DINOFLAGELLATES

  19. PROTISTS: PROTOZOA, ALGAE AND NOW FUNGUS-LIKE  • GET THEIR ENERGY BY DECOMPOSING MATTER • REPRODUCE BY SPORES • EXAMPLES: PLASMODIAL SLIME MOLDS WATER MOLDS
