Presentation Transcript

  1. Warm-Up Friday 3/22/13 • List 1 similarity of virus and bacteria. • List 1 difference of virus and bacteria.

  2. Protist and Fungi Notes Protists and Fungi Notes

  3. Objectives • Compare & Contrast the characteristics of protists & fungi. • List real world organisms that belong to kingdom Protista &kindgom Fungi.

  4. Kingdom Protista

  5. Common characteristics of Protists • Domain Eukarya/Kingdom Protista • All eukaryotic • Live in water or moist surroundings • Most unicellular, some multicellular • Autotrophs, Heterotrophs, or both

  6. 3 Categories of Protists(based on nutrition) 1) Animal Like- heterotrophs (eat other organisms) 2) Plant Like- autotrophs (contain chloroplast & photosynthesize) 3) Fungus Like- decomposers ( break down dead matter) Didinium eating Paramecium Green like plants! Water mold

  7. Animal Like Protist Types of Movement 1.) Cilia= tiny hair-like projections - used movement & feeding

  8. Animal Like Protist 2.) Pseudopod= “false feet” - cell membrane pushed 1 direction - cytoplasm flows into the bulge - allows protozoan to “drag” rest of cell behind it

  9. Animal Like Protist • Form 2 pseudopods • surrounds & traps food. • Then breaks down food • Uses food vacuole

  10. Animal Like Protists 3.) Flagella= Whip-like structures - used movement

  11. Animal Like Protists • Why do we care? • Harmful: cause disease EX: malaria & African sleeping sickness • Beneficial: food source

  12. Plant Like Protists • Most Algae • Autotrophs (photosynthesis) • Recycle sewage & waste materials • Algal blooms • harmful when overgrown • can deplete nutrients • Low O2 levels kill fish • Red Tides cause illness, paralysis, & death.

  13. Plant Like Protists • Red Algae • Green Algae • Brown Algae

  14. Fungus Like Protist • Heterotrophs • Decomposers • Have cell walls • Not in Kingdom Fungi • can move at 1 point in lives • Example: Mildew, Water Mold, & Slime Mold

  15. Other Protozoans Sporozoans= parasites that feed on cells & body fluids of host Ex. Plasmodium- live in mosquitos

  16. Kingdom Fungi

  17. Common characteristics of Fungi • Domain Eukarya/Kingdom Fungi • Eukaryotes • Decomposers • Use spores to reproduce • Need warm, moist places to grow • Examples: yeast, molds, & mushrooms.

  18. Fungi-Obtaining food Hyphae= threadlike tubes that obtain food • Grows hyphae into food • Secretes digestive chemicals • Absorb broken down food

  19. Fungi Reproduction • Fungi release 1,000’s spores • Carried by water & air (asexual reproduction) • Spores land warm, moist area & begin to grow

  20. Yeast • Reproduce by budding • Unicellular • Will grow from “mother” cell • break off • form new cell

  21. Classifications of Fungi • Threadlike= spores look like thread (hyphae) Ex. Bread Mold 2) Sac= spores look like sacs Ex. Yeast

  22. Classification of Fungi 3) Club= spores look like clubs Ex. Mushroom 4) Imperfect= canNOT reproduce sexually Ex. Penicillin

  23. Summary Draw a line in your notes for your 3-5 sentence summary.

  25. Warm Up Monday 3/25/13 1) Which virus life cycle integrates the virus DNA into the host DNA?

  26. Pond Water Lab

  27. Warm-Up Tueday 3/26/13 • List the three categories of protists. ( hint: based off of nutrition )

  28. Gems of Wisdom

  29. Warm Up Wednesday 3/27/13 1) What is the difference between an aerobe and a facultative aerobe?

  30. Unit Test
